w = \frac{5}{8} or w = \frac{9}{8}

Decimal

w = 0.625, w = 1.125

Solution steps

4 = 5 ∣ - 8 w + 7 ∣ - 6

Switch sides

5 ∣ - 8 w + 7 ∣ - 6 = 4

Move

6

to the right side

5 ∣ - 8 w + 7 ∣ = 10

Divide both sides by

5

∣ - 8 w + 7 ∣ = 2

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 8 w + 7 = - 2 or - 8 w + 7 = 2

- 8 w + 7 = - 2 or - 8 w + 7 = 2

w = \frac{5}{8} or w = \frac{9}{8}

∣ 6 r + 4 ∣ = 6 r + 4

2 ∣ - 6 x + 2 ∣ + 1 = 21

15 = x + ∣ x - 5 ∣

3 ∣ 2 x - 3 ∣ + 2 = 2

4 ∣ x ∣ - 11 = 25 - 2 ∣ x ∣
