Simplifying
0.12(y + -3) + 0.18y = 0.02y + -0.03(40)

Reorder the terms:
0.12(-3 + y) + 0.18y = 0.02y + -0.03(40)
(-3 * 0.12 + y * 0.12) + 0.18y = 0.02y + -0.03(40)
(-0.36 + 0.12y) + 0.18y = 0.02y + -0.03(40)

Combine like terms: 0.12y + 0.18y = 0.3y
-0.36 + 0.3y = 0.02y + -0.03(40)

Multiply -0.03 * 40
-0.36 + 0.3y = 0.02y + -1.2
