3 ∣ 8 + 2 x ∣ - 2 = 13

x = - \frac{13}{2} or x = - \frac{3}{2}

Decimal Notation

x = - 6.5, x = - 1.5

Solution steps

3 ∣ 8 + 2 x ∣ - 2 = 13

Move

2

to the right side

3 ∣ 8 + 2 x ∣ = 15

Divide both sides by

3

∣ 8 + 2 x ∣ = 5

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

8 + 2 x = - 5 or 8 + 2 x = 5

8 + 2 x = - 5 or 8 + 2 x = 5

x = - \frac{13}{2} or x = - \frac{3}{2}

x^{2} + 2 x - 15 \geq 0
