Question 386880: This is the equation; I was suppose to eliminate.
This is an excample of one of my problems:
{p+4q=23
{-p+q=2
Now my teacher told me to add a one front of the q; so now it would be...
[p+4q=23
[-p+1q=2
Then we put a "+" sign on the left side and add;
so it would be; 5q over 5 = 25 over 5 p+4q=23
q=5 p+4(5)=23
p+20=23
-20-20
p=3
(3,5) and it must be in alphaebetical order
p,q
*This is the problem I need help with:
{y-2x=0
{6y+2x=0

You can put this solution on YOUR website!
# 1 is correct

# 2
y-2x=0
6y+2x=0

7y = 0
y = 0

y-2x=0
0-2x=0
-2x=0
x=0

Answer: (0,0)
