-17 + -5m = 13
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '17' to each side of the equation.
-17 + 17 + -5m = 13 + 17
Combine like terms: -17 + 17 = 0
0 + -5m = 13 + 17
-5m = 13 + 17
Combine like terms: 13 + 17 = 30
-5m = 30
Divide each side by '-5'.
m = -6
Simplifying
m = -6
