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

Add '-0.2a' to each side of the equation.
0.1a + -0.2a = 0.4 + 0.2a + -0.2a

Combine like terms: 0.1a + -0.2a = -0.1a
-0.1a = 0.4 + 0.2a + -0.2a

Combine like terms: 0.2a + -0.2a = 0.0
-0.1a = 0.4 + 0.0
-0.1a = 0.4

Divide each side by '-0.1'.
a = -4

Simplifying
a = -4
