-20 + -13 + 8a + -7a = -1(4 + -6a) + (-1a) + 3

Combine like terms: -20 + -13 = -33
-33 + 8a + -7a = -1(4 + -6a) + (-1a) + 3

Combine like terms: 8a + -7a = 1a
-33 + 1a = -1(4 + -6a) + (-1a) + 3
-33 + 1a = (4 * -1 + -6a * -1) + (-1a) + 3
-33 + 1a = (-4 + 6a) + (-1a) + 3

Reorder the terms:
-33 + 1a = -4 + 3 + 6a + (-1a)

Combine like terms: -4 + 3 = -1
-33 + 1a = -1 + 6a + (-1a)
