Move all terms containing a to the left, all other terms to the right.

Add '-1a' to each side of the equation.
-1a + ab = a + -3ab + -1a + b

Reorder the terms:
-1a + ab = a + -1a + -3ab + b

Combine like terms: a + -1a = 0
-1a + ab = 0 + -3ab + b
-1a + ab = -3ab + b

Add '3ab' to each side of the equation.
-1a + ab + 3ab = -3ab + 3ab + b

Combine like terms: ab + 3ab = 4ab
-1a + 4ab = -3ab + 3ab + b

Combine like terms: -3ab + 3ab = 0
-1a + 4ab = 0 + b
-1a + 4ab = b

Combine like terms: b + -1b = 0
-1a + 4ab + -1b = 0
