x = - \frac{41}{2} or x = \frac{15}{2}

Decimal Notation

x = - 20.5, x = 7.5

Solution steps

∣ 2 x + 13 ∣ = 28

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 x + 13 = - 28 or 2 x + 13 = 28

2 x + 13 = - 28 or 2 x + 13 = 28

x = - \frac{41}{2} or x = \frac{15}{2}

∣ 9 x + 2 ∣ = 1

∣ u - 1 ∣ = 1

∣ - 7 g ∣ + 5 = 8

10 = 2 ∣ v ∣

- ∣ 3 (x + 5) (x - 1) ∣ - 1 = - 6
