-13 + -9 + 4a + -3a = -1(6 + -5a) + (-1a) + 5

Combine like terms: -13 + -9 = -22
-22 + 4a + -3a = -1(6 + -5a) + (-1a) + 5

Combine like terms: 4a + -3a = 1a
-22 + 1a = -1(6 + -5a) + (-1a) + 5
-22 + 1a = (6 * -1 + -5a * -1) + (-1a) + 5
-22 + 1a = (-6 + 5a) + (-1a) + 5

Reorder the terms:
-22 + 1a = -6 + 5 + 5a + (-1a)

Combine like terms: -6 + 5 = -1
-22 + 1a = -1 + 5a + (-1a)
