To solve for x using the addition property of equality, we need to isolate x on one side of the equation by performing the opposite operation of addition, which is subtraction.
x + 7 = 23
x = 23 - 7
x = 16
To check our answer, we can substitute x = 16 back into the original equation:
16 + 7 = 23
23 = 23
Since the equation is true when x = 16, our solution is correct. So, x = 16.
Solve using the addition property of equality. Don't forget to check.
