Question

Solve 7(3 − p) − p ≥ 8p + 5 for p.

Answer 1

p ≤ 1

Explanation:

Given

7(3 - p) - p ≥ 8p + 5 ← distribute left side and simplify

21 - 7p - p ≥ 8p + 5

21 - 8p ≥ 8p + 5 ( subtract 8p from both sides )

21 - 16p ≥ 5 ( subtract 21 from both sides )

- 16p ≥ - 16

Divide both sides by - 16, reversing the symbol as a result of dividing by a negative quantity

p ≤ 1
