-3|r-4|-7=-22

- 3 ∣ r - 4 ∣ - 7 = - 22

r = - 1 or r = 9

Solution steps

- 3 ∣ r - 4 ∣ - 7 = - 22

Move

7

to the right side

- 3 ∣ r - 4 ∣ = - 15

Divide both sides by

- 3

∣ r - 4 ∣ = 5

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

r - 4 = - 5 or r - 4 = 5

r - 4 = - 5 or r - 4 = 5

r = - 1 or r = 9

7 ∣ 2 - 11 x ∣ = 21

- 5 ∣ 7 x - 2 ∣ + 3 x = 3 x + 10

x^{2} - ∣ x ∣ = 1

3 (∣ x + 3 ∣ + 2) = 6

∣ - 5 x ∣ = 30
