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

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

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

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

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

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

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