first you write out the equation subtract 6 from both sides then multiply both sides by 4 because if you multiply something to one side you have to do it to the other one too m = -12 you can then check work like this 6 - 12/4 = 3 6 - 3 = 3 3 = 3
(m = -12 subtract 6 from both sides) (m/4 = -3 then you multiply both sides by 4)
