Solving
0.8 + 0.2m = 0

Solving for variable 'm'.

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

Add '-0.8' to each side of the equation.
0.8 + -0.8 + 0.2m = 0 + -0.8

Combine like terms: 0.8 + -0.8 = 0.0
0.0 + 0.2m = 0 + -0.8
0.2m = 0 + -0.8

Combine like terms: 0 + -0.8 = -0.8
0.2m = -0.8

Divide each side by '0.2'.
m = -4

Simplifying
