Question

My teacher gave me multiple equations she failed to teach to solve one of them is

12(m+3x)=18(x-3m);m

solving for m

Answer 1

m = -3/11 x

Explanation:

expand the brackets

12m + 36x = 18x - 54m

collect the m's on one side and the x's on the other

12m + 54m = 18x - 36x

add/ subtract

66m = -18x

divide both sides by 66

m = -18/66 x

simplify by dividing the numerator and denominator by 6

m = -3/11 x

Take it easy on your teacher. Its one of the hardest jobs in the world. Good Luck!
