2 - 3 ∣ 7 x + 5 ∣ = - 10

x = - \frac{9}{7} or x = - \frac{1}{7}

Solution steps

2 - 3 ∣ 7 x + 5 ∣ = - 10

Move

2

to the right side

- 3 ∣ 7 x + 5 ∣ = - 12

Divide both sides by

- 3

∣ 7 x + 5 ∣ = 4

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

7 x + 5 = - 4 or 7 x + 5 = 4

7 x + 5 = - 4 or 7 x + 5 = 4

x = - \frac{9}{7} or x = - \frac{1}{7}

8 ∣ 3 - 3 x ∣ - 5 = 91

8 ∣ x + 2 ∣ = 24

3 ∣ x + 7 ∣ = 33

5 ∣ u + 8 ∣ - 70 = - 15

2 ∣ k ∣ = 4
