aaaaaaaaaaaaaaaaaaaaaa (do the opposite operation with the variable so they undo each other) ) aaaaaaaaaaaaaaaaaaaaaaa ADDITION <--> SUBTRACTION aaaaaaaaaaaaaaaaaaaaaaa MULTIPLICATION <--> DIVISION
 * ** GOAL: ** To Isolate the variable
 * ** HOW TO DO THIS: ** Use the inverse operation on the same side as the variable

1.) x + 5 = 12 : We want to get x by itself on one side of the equal sign. So the first step is to use the inverse aaaaaaaaaaaaaaaa operation of addition (SUBTRACTION)
 * STEPS TO FOLLOW: **

2.) x + 5 = 12 : So we subtract each side of the equation by 5 aaaaa -5 aa -5

3.) aa x = 7 aa : Once we use the inverse variation, we are left with x by itself and 12 - 5 equals 7. Therefore, if we aaaaaaaaaaaaaaaa plug 7 back into the original equation for x + 5 = 12, we get 7 + 5 = 12 and this is true so our aaaaaaaaaaaaaaaa answer of x = 7 is correct.
