Solution for 40.2=3(m+2) equation:

Simplifying
40.2 = 3(m + 2)

Reorder the terms:
40.2 = 3(2 + m)
40.2 = (2 * 3 + m * 3)
40.2 = (6 + 3m)

Solving
40.2 = 6 + 3m

Solving for variable 'm'.

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

Add '-3m' to each side of the equation.
40.2 + -3m = 6 + 3m + -3m

Combine like terms: 3m + -3m = 0
40.2 + -3m = 6 + 0
40.2 + -3m = 6

Add '-40.2' to each side of the equation.
40.2 + -40.2 + -3m = 6 + -40.2

Combine like terms: 40.2 + -40.2 = 0.0
0.0 + -3m = 6 + -40.2
-3m = 6 + -40.2

Combine like terms: 6 + -40.2 = -34.2
-3m = -34.2

Divide each side by '-3'.
m = 11.4

Simplifying
m = 11.4
