Answer:
I will assume you are trying to find x and y. x = -1, y = 0=9
Step-by-step explanation:
Multiply the second equation by 7 and subtract the two.
14x + 5y = 31
-(14x - 21y = -203)
This gives 26y = 234. Divide both sides by 26. y = 9
Then substitute y into any equation. I'll use 2x - 3y = -29
2x -3(9) = -29
2x - 27 = -29
2x = -2
x = -1
