14 + -12x = -34 + -12x + 14 + -34

Reorder the terms:
14 + -12x = -34 + 14 + -34 + -12x

14 + -12x = -20 + -34 + -12x

Combine like terms: -20 + -34 = -54
14 + -12x = -54 + -12x

Add '12x' to each side of the equation.
14 + -12x + 12x = -54 + -12x + 12x

Combine like terms: -12x + 12x = 0
14 + 0 = -54 + -12x + 12x
14 = -54 + -12x + 12x

Combine like terms: -12x + 12x = 0
14 = -54 + 04 = -54
