If I understand your question correctly, you need to turn the decimal into a fraction.
It would be better if you posted a problem.

3/4(b+8)=15
You need to also distribute the 3/4 to 8;
(b)+(8)=15
b+=15
b+6=15
b=9
Now multiply each side by the reciprical of , which is ;
b=(9)
b=
b=12

Do you mean when your are given a table of x and y points?
ex.
x|y
---
0|2
1|3
2|1
your points would be;
(0,,2), (1,3), (2,1)
You would plott those on the graph, then draw a line connecting them.
Hope I understood what you were asking, it is a little difficult to understand some of the questions completely because you are limited to the way you can ask a queastion.
Hope I got it

You start by making a table and choosing values for x and then solving the equation for y.
y-x=-5
when x=0;
y-(0)=-5
y=-5
then y=-5
when x=1
y-(1)=-5
y=-5+1
y=-4
then y=-4
when x=2
y-(2)=-5
y=-5+2
y=-3
then y=-3
Now you have three points, so you plot them on the graph and draw a line connecting them.

The product of a number and 3 is twice the sum of that number and five.
let x= the number
"the product" meansanswer to multiplication, so;
3x= the product of a number and 3;
"is" means =;
"sum' meansanswer to an addition;
"sum of that number and 5";
x+5;
"of" means multiply;
"twicw the sum"
2(x+5);
3x=2(x+5)
3x=2x+10
3x-2x=10
x=10

(4n+5)x5=-n-24
Is that 5x outside the parenthesis or *5?
I'm assuming it is *5, if so;
(4n+5)*5=-n-24
distribute the 5;
20n+25=-n-24
add n tto both sides;
20n+25+n=-24
subtract 25 to both sides;
21n=-24-25
21n=-49
divide each side by 21;
n=
n=

2y+x=-3.
There are diffeerent ways to solve this. One way is to choose some easy points for x, (say 0, 1, and 2), plug them in, and calculate the corresponding y-values.
2y+(0)=-3
2y=-3
y=-3/2
First point; (0,-3/2)
2y+(1)=-3
2y=-3-1
2y=-4
y=-2
2nd point;
(1,-2)
2y+(2)=-3
2y=-3-2
2y=-5
y=-5/2
3rd point;
(2,-5/2)
Now plot these points on a graph, and you have your line.
hope you understand

First add like terms;
13-7f=25(5)
13-7f=125
now subtract 13 from both sides;
-7f=125-13
-7f=112
divide each side by -7;
f=-16
Hope you understand

To graph a linear inequality in two variables (say, x and y), first get y alone on one side. Then consider the related equation obtained by changing the inequality sign to an equals sign. The graph of this equation is a line.
If the inequality is strict (< or >), graph a dashed line. If the inequality is not strict ( or ), graph a solid line.
Example:
Graph the inequality .

Now, substitute x = 0, y = 0 to decide whether (0, 0) satisfies the inequality

This is false. So, shade the half-plane which does not include the point (0, 0).
Hope this helps

a)You need to add her hieght at the beginning of the year to how much she grew.
62 1/2 + 1 3/4 = 62 2/4 + 1 3/4=62 5/4= 63 1/4
b)Now subtract 1/8 from 1 3/4,
1 3/4 - 1/8 = 1 5/8
Now subtract that from 62 1/2
62 1/2 - 1 5/8= 60 7/8
So her hieght at the beginningof last year was - 60 7/8

6=-4+h
Add 4 to both sides
6+4=-4+h=4
10=h
-7+d=-3
add 7 to both sides;
-7+d+7=3+7
d=10
9=m+11
Subtract both sides by 11;
9-11=m+11-11
-2=m
f+(-9)=-19
add 9 to both sides;
f+(-9)+9=-19+9
f=-10

What was the original problem?

You can put this solution on YOUR website!
You are already given what one variable =, so plug that into the equation to solve for the other variable.
1)2x+7y=3 x=1-4y
2(1-4y)+7y=3
2-8y+7y=3
2-y=3
y=3-2
y=1
2x+7(1)=3
2x+7=3
2x=3-7
2x=-4
x=-2
See if you can solve the others, if you have problems let me know.

Diregard the other answers I sent to you. I pressed the wrong button.
Start by solving each inequality for y; and put in slope y-intercept form, y=mx+b;

y>-x+5
They both are already is in slope intercept form;
The first one;
your y-intercept = 3
secnd one;
y-intercept=5
So what you do on the graph is plot points at your y-intercept;
Now your first slope=2
second slope=-1

Now the important part is the shading. since the first eq. is < and = to, you are going to make it a solid line and shade the area BELOW the line.
The second eq.is > so you are going to make the line dotted and shade the area ABOVE the line.
Hope you understand

Is the answer 15 or -15? I keep coming up with -15.
x-{3x-[2x-(8-x)+2]+3}-6=0
It sounds like you are forgetting the -1 outside the parenthesis and brackets.
You need to distribute that before you add like terms.
x-{3x-[2x-8+x+2]+3}-6=0
Now add like terms in brackets;
x-{3x-[x-6]+3}-6=0
Now distribute the -1 outside the brackets;
x-{3x-x+6+3}-6=0
Add like terms inside parenthesis;
x-{2x+9}-6=0
now distribute the -1 again outside the par;
x-2x-9-6=0
-x-15=0
-x=15
x=-15

First of all you need to do what is in the parenthesis;


Now you multiply the exponents;


A negative exponent turns it into a fraction;
