Answer (2)

what you do is to substitute the first number for x and the second for y:
(x+7)y=10
a):
(-9+7) -5=10 (-2) -5=10 10=10
yes, it's a solution!
b) (-8+7)10=10 -1*10=10 -10=10
no, not a solution!
c) (-2+7)2=10 5*2=10 yes, a solution!!
d) (3+7)*5=10 50=10
no, not a solution!

The solutions to the equation \((x + 7)y = 10) are the ordered pairs (-9, -5) and (-2, 2) . The pairs (-8, 10) and (3, 5) do not satisfy the equation. Therefore, the correct answers are A and C.
