m=3(2m-(-10))

Solution for m=3(2m-(-10)) equation:

Simplifying
m = 3(2m + -1(-10))

Multiply -1 * -10
m = 3(2m + 10)

Reorder the terms:
m = 3(10 + 2m)
m = (10 * 3 + 2m * 3)
m = (30 + 6m)

Solving
m = 30 + 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.
m + -6m = 30 + 6m + -6m

Combine like terms: m + -6m = -5m
-5m = 30 + 6m + -6m

Combine like terms: 6m + -6m = 0
-5m = 30 + 0
-5m = 30

Divide each side by '-5'.
m = -6
