How do you solve equations that contain addition or subtraction?
I can solve equations that contain addition or subtraction by using 2 properties of equality, the "Addition Property of Equality" or APOE and the "Subtraction Property of Equality" or SPOE. Then, I can use the IPOA (Identitive Property of Addition). Finally, I can solve the Equation.
Example: x+5=14
step 1. move the numbers, constant with constant and variable with variable, Remember, you MUST change the operation first (x=14-5)
step 2. solve (14-5=9; x=9)
