- 4 + 2 ∣ 5 x + 1 ∣ = 16

x = - \frac{11}{5} or x = \frac{9}{5}

Solution steps

- 4 + 2 ∣ 5 x + 1 ∣ = 16

Move

4

to the right side

2 ∣ 5 x + 1 ∣ = 20

Divide both sides by

2

∣ 5 x + 1 ∣ = 10

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

5 x + 1 = - 10 or 5 x + 1 = 10

5 x + 1 = - 10 or 5 x + 1 = 10

x = - \frac{11}{5} or x = \frac{9}{5}

(x) = 4 ∣ x + 6 ∣

2 ∣ x + 3 ∣ + 7 = 3

∣ x - a ∣ = 0

∣ 2 c - 13 ∣ = 66

∣ - 9 b + 6 ∣ - 5 = 7
