Assuming this is a system of equations, here is how to find x.
2x + 3y = 45
x + y = 10
Multiply x + y = 10 by 2 so you are able to use the elimination method.
2x + 3y = 45
2x + 2y = 20
Subtract.
y = 25
Now that we've found y, we can plug it in to find x.
x + 25 = 10
Subtract 25 from both sides.
x = -15
-7 + -3 = -10 So.... it can be any negative integers that would equal -10.
EX: -6 + -4 = -10 or -5 + -5 = -10
Answer:
The correct equation is D.) 6x - 7y = -11
