xplus4equals43

Answer 1

To solve for x using the addition property of equality, we need to isolate x on one side of the equation.

Given: x + 4 = 43

Subtract 4 from both sides:
x + 4 - 4 = 43 - 4
x = 39

Therefore, x = 39.

To check our answer, we substitute x = 39 back into the original equation:
39 + 4 = 43
43 = 43

Since the equation is true, our solution x = 39 is correct.
