To solve the equation x - 5 = 7 using the addition property of equality, we need to isolate the variable x by adding 5 to both sides of the equation.
x - 5 + 5 = 7 + 5
x = 12
Now, we need to perform a check by substituting x = 12 back into the original equation:
12 - 5 = 7
7 = 7
Since the equation holds true, the solution x = 12 is correct.
x - 5 + 5 = 7 + 5
x = 12
Now, we need to perform a check by substituting x = 12 back into the original equation:
12 - 5 = 7
7 = 7
Since the equation holds true, the solution x = 12 is correct.
