Flip the equation.

3m-12=39
and add 12 to both sides.

3m-12+12=39+12

3m=51
Now divide both sides by 3.

(3m)/(3)
= (51)/(3)


Final answer: m=17

To solve for m;

39 = 3m -12

39+12 = 3m -12 + 12 (add 12 to both sides)

51 = 3m

51 ÷ 3 = m

17 =m

m =17

Hope that helps, let me know if you don't understand something :D
