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

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.
\(\frac{3m}{3}\)\(= \frac{51}{3}\)


Final answer: m=17
