How do you solve - 5 (m-3) + 2 (3m+1) = 15-8

-5 (m-3) + 2 (3m+1) = 15-8

Multiply the numbers outside of the parenthesis with the numbers inside the parenthesis

(-5m+15) + (6m+2) = 15-8

Add 6m to - 5m and add 2 to 15

m+17=15-8

Subtract 8 from 15

m+17=7

Subtract 17 from 7

Final Answer: m = - 10
