Simplifying

3m + 5 = 4m -10

Reorder the terms:

5 + 3m = 4m -10

Reorder the terms:

5 + 3m = -10 + 4m

Solving

5 + 3m = -10 + 4m

Solving for variable 'm'.

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

Add '-4m' to each side of the equation.

5 + 3m + -4m = -10 + 4m + -4m

Combine like terms: 3m + -4m = -1m

5 + -1m = -10 + 4m + -4m

Combine like terms: 4m + -4m = 0

5 + -1m = -10 + 0

5 + -1m = -10

Add '-5' to each side of the equation.

5 + -5 + -1m = -10 + -5

Combine like terms: 5 + -5 = 0

0 + -1m = -10 + -5

-1m = -10 + -5

Combine like terms: -10 + -5 = -15

-1m = -15

Divide each side by '-1'.

m = 15

Simplifying

m = 15
