Question

5m - 7 = 3(2m + 1).

Answer 1

The answer is M= -10

Answer 2

m = -10

Explanation:

5m-7 = 3(2m+1) distribute multiplication by 3 over the addition 2m+1

5m-7 = 3·2m+3·1

5m-7 = 6m+3, subtract 5m and 3 from both sides of equal sign

5m-5m-7-3 = 6m -5m +3-3

-7-3 = 6m -5m combine like terms

-10 = m
