1.) You add 18 to both sides          2.) You add 10 to both sides
    y = 6x - 18                                         y = 4x - 10
+18        +18                                      +10        +10
then you divide by 6                       then you divide by 4   
18 = 6x                                           10 = 4x
/6     /6                                             /4    /4
where x is equal to 3                      where x is equal to 2.5
x = 3                                                x = 2.5
