Simplifying
0.2(x + -2) + -0.4(x + 2) = -0.2x + -0.4

Reorder the terms:
0.2(-2 + x) + -0.4(x + 2) = -0.2x + -0.4
(-2 * 0.2 + x * 0.2) + -0.4(x + 2) = -0.2x + -0.4
(-0.4 + 0.2x) + -0.4(x + 2) = -0.2x + -0.4

Reorder the terms:
-0.4 + 0.2x + -0.4(2 + x) = -0.2x + -0.4
-0.4 + 0.2x + (2 * -0.4 + x * -0.4) = -0.2x + -0.4
-0.4 + 0.2x + (-0.8 + -0.4x) = -0.2x + -0.4
