Question

-3x-7y=-66
-10x-7y=-24

Answer 1

Are you just solving for x and y?

Answer 2

Well I'm not sure if you still needed the answer, but x=-6 and y=12

To solve this, I used elimination and distributed a -1 in the equation -10x-7y=-24. I then added down and divided by 7 to isolate the x; finally getting x=-6.

To solve for y you can simply plug in the variable x into any of the two original problems. I replaced the x in the equation -3x-7y=-66; then multiplied -3 and -6. I subtracted 18 by both sides then divided by -7.
