9 - 2 ∣ 2 x + 1 ∣ = 5

x = - \frac{3}{2} or x = \frac{1}{2}

Decimal Notation

x = - 1.5, x = 0.5

Solution steps

9 - 2 ∣ 2 x + 1 ∣ = 5

Move

9

to the right side

- 2 ∣ 2 x + 1 ∣ = - 4

Divide both sides by

- 2

∣ 2 x + 1 ∣ = 2

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 x + 1 = - 2 or 2 x + 1 = 2

2 x + 1 = - 2 or 2 x + 1 = 2

x = - \frac{3}{2} or x = \frac{1}{2}

x^{2} + x - 6 = x + 1

∣ 5 x + 7 ∣ - 9 = 3 x

∣ 2 x - 4 ∣ + 8 = x

2 ∣ 9 - 2 x ∣ - 9 = 1

x^{2} - 20 x - 1 = 20
