Answer:

Since x= -3y + 6

Substitute this into equation 2

You now have equation 2 as

2(-3y+6) + 8y = -12

-6y + 12 + 8y = -12

8y - 6y = -12 -12

2y = -24

y= -12

x = -3(-12) + 6

x= 36 + 6

x= 42.

Answer:

x + 3y = 6

2x + 8y = -12

substracting first equation from the second will give us

x - 5y = -18

subtracting the first one from this will give us

-8y = -24

y = 3

x = -3
