- 5 - 5 ∣ - 5 r - 4 ∣ = - 100

r = - \frac{23}{5} or r = 3

Decimal

r = - 4.6, r = 3

Solution steps

- 5 - 5 ∣ - 5 r - 4 ∣ = - 100

Move

5

to the right side

- 5 ∣ - 5 r - 4 ∣ = - 95

Divide both sides by

- 5

∣ - 5 r - 4 ∣ = 19

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 5 r - 4 = - 19 or - 5 r - 4 = 19

- 5 r - 4 = - 19 or - 5 r - 4 = 19

r = - \frac{23}{5} or r = 3

∣ 6 x + 4 ∣ - 2 = 14

∣ y - 9 ∣ = 0

- 20 = - 3 ∣ 6 w - 9 ∣ - 5

2 ∣ - 5 - 4 n ∣ + 6 = - 8

∣ 3 h ∣ = 3
