9|-2r-4|+6=60

9 ∣ - 2 r - 4 ∣ + 6 = 60

r = - 5 or r = 1

Solution steps

9 ∣ - 2 r - 4 ∣ + 6 = 60

Move

6

to the right side

9 ∣ - 2 r - 4 ∣ = 54

Divide both sides by

9

∣ - 2 r - 4 ∣ = 6

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 2 r - 4 = - 6 or - 2 r - 4 = 6

- 2 r - 4 = - 6 or - 2 r - 4 = 6

r = - 5 or r = 1

∣ 1 + 7 x ∣ - 7 = 3

∣ x ∣ = - 19

- 1 = ∣ 7 v ∣ - 1

45 = ∣ 3 t ∣

2 ∣ d + 3 ∣ - 6 = 8
