3-|6-12r|=-51

3 - ∣ 6 - 12 r ∣ = - 51

r = - 4 or r = 5

Solution steps

3 - ∣ 6 - 12 r ∣ = - 51

Move

3

to the right side

- ∣ 6 - 12 r ∣ = - 54

Divide both sides by

- 1

∣ 6 - 12 r ∣ = 54

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

6 - 12 r = - 54 or 6 - 12 r = 54

6 - 12 r = - 54 or 6 - 12 r = 54

r = - 4 or r = 5

∣ 2 k + 1 ∣ = 7

4 + 2 ∣ 8 - x ∣ = 15

∣ x - 6 ∣ + 2 x + 5 = 3

21 = ∣ 7 c ∣

∣ 100 - 5 x ∣ = 50
