∣ 8 x - 2 ∣ = 66

x = - 8 or x = \frac{17}{2}

Solution steps

∣ 8 x - 2 ∣ = 66

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

8 x - 2 = - 66 or 8 x - 2 = 66

8 x - 2 = - 66 or 8 x - 2 = 66

x = - 8 or x = \frac{17}{2}

\frac{x}{3} - 2 = 4

10 - 3 ∣ 3 + 6 x ∣ = 1

∣ 5 y - 7 ∣ + 2 = 4

- 8 ∣ 10 k ∣ = - 480
