[tex]2(x+4)=18\ \ \ \ | omiting\ the\ bracket\\\\ 2x+8=18\ \ \ | subtract\ 8\\\\ 2x=10 \ \ \ \ | divid\ by\ 2 \\\\\x=5[/tex]
                                      2(x+4) = 18
expand the equation     2x + 8 = 18
subtract 8                      2x = 10
divide by 2                    x = 5
or
                                     2(x+4) = 18
divide by 2                    x+4 = 9
subtract 4                     x = 5
Remember, whatever you to one side, you do to the other. Your goal is to isolate X!
