Question

solve for m : -3(m-2n)= 5m

Answer 1

The answer is m = 3n/4.

-3m + 6n = 5m
6n = 5m + 3m
6n = 8m
6n/8 = m
3n/4 = m
m = 3n/4

Answer 2

-3(m-2n)=5m             (distribute the negative 3)

-3m+6n=5m                 (add 3m to both sides)

6n= 8m                           (now divide by 8 to solve for m)

6n/8=m                           you can simplify

3/4n=m
