Question

PLEASE HELP I AM BEHIND!!!!

If the solution to an equation is x = −5, what could the original equation be?

A. x + 3 = 8
B. x − 3 = 8
C. x + 8 = 3
C. x − 8 = 3

(sorry if this is easy for you, I'm bad at math.)

Answer 1

C. x + 8 = 3

Explanation:

x + 8 = 3

x + 8 - 8 = 3 - 8 ( so do the same thing you do on both the left and right side )

x = -5

So C is correct but you can always say 3 - 8 to figure out that the answer in c is the right one.
