Question

-2x+15y=-24
2x+9y=24

Answer 1

Answer: x = 12 y = 0

Explanation:

Answer 2

x = 12 and y = 0

Explanation:

Use elimination by adding the equations together.

-2x + 15y =-24

2x + 9y = 24

---------------

24y = 0

y=0

Then substitute y = 0 into one equation to find x.

-2x + 15(0) = -24

-2x + 0 = -24

-2x = -24

x = 12
