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

Add '-0.1x' to each side of the equation.
6 + 0.3x + -0.1x = 2 + 0.1x + -0.1x

Combine like terms: 0.3x + -0.1x = 0.2x
6 + 0.2x = 2 + 0.1x + -0.1x

Combine like terms: 0.1x + -0.1x = 0.0
6 + 0.2x = 2 + 0.0
6 + 0.2x = 2

Add '-6' to each side of the equation.
6 + -6 + 0.2x = 2 + -6

Combine like terms: 6 + -6 = 0
0 + 0.2x = 2 + -6
0.2x = 2 + -6

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

Divide each side by '0.2'.
x = -20

Simplifying
x = -20
