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.) 3 **x** + 6 = 24 : The first step is to isolate the variable (x) by getting rid of the 3 and 6. Always aaaaaaaaaaaaaa get rid of addition or subtraction first. So we want to get rid of the + 6.
 * STEPS TO FOLLOW: **

2.) 3 **x** + 6 = 24 : Because the problem adds 6, the inverse or opposite would be to subtract 6 aaaaa aaa -6 ​ aaaa from both sides.

3.) aa 3 **x** = 18 aa : Now we are left with one step to complete. The inverse operation of multiplication aaaa /3 aaa /3 aaa is division, so we need to divide each side by 3.

4.) aa **x** = 6 a aa  : We are finally left with x 6.   If we plug 6 back into the original equation, we get aaaaaaaaaaaaaa 3( **6** ) + 6 = 24 which is true. Therefore, x = 6 is correct.
