8|x-9|=64

8 ∣ x - 9 ∣ = 64

x = 1 or x = 17

Solution steps

8 ∣ x - 9 ∣ = 64

Divide both sides by

8

∣ x - 9 ∣ = 8

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x - 9 = - 8 or x - 9 = 8

x - 9 = - 8 or x - 9 = 8

x = 1 or x = 17

1 = x^{2} - 2

∣ 12 - 4 c ∣ = 15

3 - 2 ∣ 2 j - 5 ∣ = - 4

∣ x - 3 ∣ + 2 = 18

∣ k ∣ - 7 = - 7
