Solving
4.16 + 4m = 12

Solving for variable 'm'.

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

Add '-4.16' to each side of the equation.
4.16 + -4.16 + 4m = 12 + -4.16

Combine like terms: 4.16 + -4.16 = 0.00
0.00 + 4m = 12 + -4.16
4m = 12 + -4.16

Combine like terms: 12 + -4.16 = 7.84
4m = 7.84

Divide each side by '4'.
m = 1.96

Simplifying
m = 1.96
