-15 + -8 + 3r + 2r = -2(r + -1) + 8(r + 2)

Combine like terms: -15 + -8 = -23
-23 + 3r + 2r = -2(r + -1) + 8(r + 2)

Combine like terms: 3r + 2r = 5r
-23 + 5r = -2(r + -1) + 8(r + 2)

Reorder the terms:
-23 + 5r = -2(-1 + r) + 8(r + 2)
-23 + 5r = (-1 * -2 + r * -2) + 8(r + 2)
-23 + 5r = (2 + -2r) + 8(r + 2)

Reorder the terms:
-23 + 5r = 2 + -2r + 8(2 + r)
-23 + 5r = 2 + -2r + (2 * 8 + r * 8)
-23 + 5r = 2 + -2r + (16 + 8r)
