Add '-3' to each side of the equation.
3 + a + -3 + -1b = 0 + -3

Reorder the terms:
3 + -3 + a + -1b = 0 + -3

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

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

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

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

Simplifying
a = -3 + b
Solution
a = {0, -3 + b}
