Add '-1a' to each side of the equation.
-1a + ab = 5 + a + -1a + b

Combine like terms: a + -1a = 0
-1a + ab = 5 + 0 + b
-1a + ab = 5 + b

Reorder the terms:
-5 + -1a + ab + -1b = 5 + b + -5 + -1b

Reorder the terms:
-5 + -1a + ab + -1b = 5 + -5 + b + -1b

Combine like terms: 5 + -5 = 0
-5 + -1a + ab + -1b = 0 + b + -1b
-5 + -1a + ab + -1b = b + -1b

Combine like terms: b + -1b = 0
-5 + -1a + ab + -1b = 0
