Answer:
A
Step-by-step explanation:
substitute the values from the replacement set into the right side of the equation to find which values of x make the equation true.
x = - 32
+ 5 = - 8 + 5 = - 3 ← True
x = 8
+ 5 = 1 + 5 = 6 ≠ - 3 ← False
x = 32
+ 5 = 8 + 5 = 13 ≠ - 3 ← False
the solution is therefore x = - 32
