6 + 0.4x = 4 + 0.2x

Solving for variable 'x'.

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

Add '-0.2x' to each side of the equation.
6 + 0.4x + -0.2x = 4 + 0.2x + -0.2x

Combine like terms: 0.4x + -0.2x = 0.2x
6 + 0.2x = 4 + 0.2x + -0.2x

Combine like terms: 0.2x + -0.2x = 0.0
6 + 0.2x = 4 + 0.0
6 + 0.2x = 4

Add '-6' to each side of the equation.
6 + -6 + 0.2x = 4 + -6

Combine like terms: 6 + -6 = 0
0 + 0.2x = 4 + -6
0.2x = 4 + -6

Combine like terms: 4 + -6 = -2
0.2x = -2

Divide each side by '0.2'.
x = -10

Simplifying
x = -10
