Question

Use elimination to solve the system:
6x-4y=6
-6x+3y=0

Answer 1

6x+4y=6
-6x+3y=0

7y=6
y=6/7

use one of the equations above i picked the first one
6x+4y=6
6x+4(6/7)=6
6x+24/7=42/7
6x=18/7
x=3/7

Answer 2

6x and -6x cancel each other out.
You are left with -1y=6
Therefore, y=-6

6x-4(-6)=6
6x+24=6
Subtract 24 from both sides.

6x=-18
Divide both sides by 6
X=-3

Final answers: x=-3 y=-6
