Simplifying
2(90 + -1p) + -1(p + -50) = (p + 30) + -1(p + 10)
(90 * 2 + -1p * 2) + -1(p + -50) = (p + 30) + -1(p + 10)
(180 + -2p) + -1(p + -50) = (p + 30) + -1(p + 10)

Reorder the terms:
180 + -2p + -1(-50 + p) = (p + 30) + -1(p + 10)
180 + -2p + (-50 * -1 + p * -1) = (p + 30) + -1(p + 10)
180 + -2p + (50 + -1p) = (p + 30) + -1(p + 10)

Reorder the terms:
180 + 50 + -2p + -1p = (p + 30) + -1(p + 10)

Combine like terms: 180 + 50 = 230
230 + -2p + -1p = (p + 30) + -1(p + 10)
