Step-by-step explanation:
Simplifying
5m + -7 = 6m + -9
Reorder the terms:
-7 + 5m = 6m + -9
Reorder the terms:
-7 + 5m = -9 + 6m
Solving
-7 + 5m = -9 + 6m
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-6m' to each side of the equation.
-7 + 5m + -6m = -9 + 6m + -6m
Combine like terms: 5m + -6m = -1m
-7 + -1m = -9 + 6m + -6m
Combine like terms: 6m + -6m = 0
-7 + -1m = -9 + 0
-7 + -1m = -9
Add '7' to each side of the equation.
-7 + 7 + -1m = -9 + 7
Combine like terms: -7 + 7 = 0
0 + -1m = -9 + 7
-1m = -9 + 7
Combine like terms: -9 + 7 = -2
-1m = -2
Divide each side by '-1'.
m = 2
Simplifying
m = 2
