Simplifying
0.02(y + -7) + 0.04y = 0.08y + -0.01(20)

Reorder the terms:
0.02(-7 + y) + 0.04y = 0.08y + -0.01(20)
(-7 * 0.02 + y * 0.02) + 0.04y = 0.08y + -0.01(20)
(-0.14 + 0.02y) + 0.04y = 0.08y + -0.01(20)

Combine like terms: 0.02y + 0.04y = 0.06y
-0.14 + 0.06y = 0.08y + -0.01(20)

Multiply -0.01 * 20
-0.14 + 0.06y = 0.08y + -0.2
