|(w+9)/7 |=2

\frac{w + 9}{7} = 2

w = - 23 or w = 5

Solution steps

\frac{w + 9}{7} = 2

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

\frac{w + 9}{7} = - 2 or \frac{w + 9}{7} = 2

\frac{w + 9}{7} = - 2 or \frac{w + 9}{7} = 2

w = - 23 or w = 5

2 ∣ x + 10 ∣ = 8 x - 16

∣ 9 + 6 x ∣ = 4

∣ 6 a + 1 ∣ + 10 = 23

∣ x + 6 ∣ = 12 + x

∣ x + 1 ∣ + 2 = x + 4
