Question

Solve by elimination
-8x+12y= 12
-2x-12y= -12

Answer 1

x=0, y=1.

Explanation:

-8x+12y= 12

-2x-12y= -12 Adding these 2 equations:

-10x = 0

x = 0.

Plug this into equation 1:

-8(0) + 12y = 12

12y = 12

y = 1.

Answer 2

X = -4

Y= -5/3

Explanation:

-8x + 12y =12

-2x + 12y = -12

Subtract equation two from equation one , we have

-6X = 24

Then divide both sides by -6.

X= - 4

Substitute X = -4 into any of the equations to get Y
