What would the answer be to this math problem 8m-9-3m+11

Simplifying:
8m + -9 + -3m + 11 = 0

Reorder the terms:
-9 + 11 + 8m + -3m = 0

Combine like terms: -9 + 11 = 2
2 + 8m + -3m = 0

Combine like terms: 8m + -3m = 5m
2 + 5m = 0

Solving:
2 + 5m = 0

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add '-2' to each side of the equation.
2 + -2 + 5m = 0 + -2

Combine like terms: 2 + -2 = 0
0 + 5m = 0 + -2
5m = 0 + -2


Combine like terms: 0 + -2 = -2
5m = -2

Divide each side by '5'.
m = -0.4

Simplifying
m = -0.4

Hope this helps :)
