First= -2x+2y+3z=0
= -2x+2y+3z +-2y=0+(-2y)
-2x+3z=-2y
-2x+3z=-2y+-3z
-2x=-2y-3z
Divide both by negative two
-2x/-2=-2y-3z/-2
x=y+3/2z that’s the answer.

Answer:
1. 4x + 6
2. -15x + 11
5. -x + 4
6. -4x + 7
9. 5x - 2
12. x + 16
Step-by-step explanation:
Remove the parenthesis for each one so everything's out in the open. Next, you group like terms. The numbers with variables on one side, and the other numbers on the other side. For example:
x + 3x - 2 + 8
Then, you combine like terms:
4x + 6
That's mostly how you do each one.
Answer:
