Does it want you to use elimination, substituion or does it not matter?

Substitution Method

anonymous · Answer

If you're using substitution you have to get one on the equations to equal y so I'll choose the first one
-3x+2y=2
Add 3x on both sides
2y=3x+2
Divide by 2 on both sides
y=3/2x+1
Now take the equation above and substitute it into the second equation you were given
So
|dw:1399296538452:dw|
Take out the y and put in (3/2x+1) and make sure it's in parentheses.

anonymous · Answer

So your equation will look like this after you substitute.
7x-3(3/2x+1)=7

That means multiply
So 3*3/2x=?
and 3*1=?
