Answer:

x=7

Step-by-step explanation:

-3+3x=18

+3       +3           (on both sides)

                         (-3+3 cancel out)

3x=18

--     --                (divid both sides by 3) (ignore by bad spelling)

3     3                (3x divided by 3 the threes cancel out)

                         (what is 18/3 ?)

x=6
