Solution steps

9 = ∣ - 3 x - 1 ∣ - 7

Switch sides

∣ - 3 x - 1 ∣ - 7 = 9

Move

7

to the right side

∣ - 3 x - 1 ∣ = 16

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 3 x - 1 = - 16 or - 3 x - 1 = 16

- 3 x - 1 = - 16 or - 3 x - 1 = 16

x = - \frac{17}{3} or x = 5

\frac{2 x - 4}{7} = 2

- 7 + 10 ∣ 6 r - 10 ∣ = 93

20 - ∣ 2 y - 6 ∣ = 10

2 ∣ x ∣ = 3

3 ∣ 16 x + 18 ∣ - 9 = 15
