Basically these questions are about making a formula.
I like #3.
Nine divided by a number is equal to three....
Make these words into numbers
9/x=3
How do you solve for x?? We must get it off the bottom by mult. both sides by x
x(9/x)=3(x)
which is 9=3x
Then divid by 3 to get x by it self..
9/3=x
3=x
try the others..if you still have problems repost the questions with where you are finding the troubles.

1.twice a number x added to one half equals nine
2x + 1/2 = 9
Subtract 1/2 from both sides
2x = 8 1/2
Divide both sides by 2
x= 4 1/4
2(4 1/4) + 1/2 = 9
2.three fourths a number is nine
3/4x = 9
To solve, multiply 9 and 3/4 (12)
3/4(12) = 9
3.nine divided by a number is equal to three
9/x = 3
3*3=9, so the answer is 3
4.six minus a number divided by two is equal to twenty one
6 - x/2=21
Subtract 6 from both sides
-x/2=15
multiply both sides by -2
x=-30
Check your answer
6-(-30)/2=21
6+15=21
21=21
5.six times a number x less four is equal to eight
6x-4=8
Add 4 to both sides
6x=12
Divide by 6 to both sides
x=2
Check:
6x-4=8
6(2)-4=8
12-4=8
8-8
