∣ 2 x - 4 ∣ = 13

x = - \frac{9}{2} or x = \frac{17}{2}

Decimal Notation

x = - 4.5, x = 8.5

Solution steps

∣ 2 x - 4 ∣ = 13

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 x - 4 = - 13 or 2 x - 4 = 13

2 x - 4 = - 13 or 2 x - 4 = 13

x = - \frac{9}{2} or x = \frac{17}{2}

∣ 2 x - 4 ∣ = 16

∣ 2 x - 4 ∣ = 18

∣ 2 x - 4 ∣ = 20

5 - ∣ 3 x + 6 ∣ = 2

- 4 ∣ U + 5 ∣ = - 40
