150=|p-150|

150 = ∣ p - 150 ∣

p = 0 or p = 300

Solution steps

150 = ∣ p - 150 ∣

Switch sides

∣ p - 150 ∣ = 150

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

p - 150 = - 150 or p - 150 = 150

p - 150 = - 150 or p - 150 = 150

p = 0 or p = 300

\frac{∣ x + 4 ∣}{- 6} = - 3

∣ a ∣ = - a

4 = ∣ z + 4 ∣

3 ∣ s - 2 ∣ = 9

∣ 3 m + 2 ∣ + 4 = 29
