15=|-3s|

15 = ∣ - 3 s ∣

s = - 5 or s = 5

Solution steps

15 = ∣ - 3 s ∣

Switch sides

∣ - 3 s ∣ = 15

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 3 s = - 15 or - 3 s = 15

- 3 s = - 15 or - 3 s = 15

s = - 5 or s = 5

∣ 2 u + 11 ∣ = 3

9 \frac{x}{4} - 10 = 8

∣ x + 11 ∣ = 14

7 - 6 ∣ - 9 x + 1 ∣ = 55

\frac{1}{5} a + 2 = 7
