x = - \frac{9}{2} or x = - \frac{7}{2}

Decimal Notation

x = - 4.5, x = - 3.5

Solution steps

- 2 ∣ x + 4 ∣ = - 1

Divide both sides by

- 2

∣ x + 4 ∣ = \frac{1}{2}

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x + 4 = - \frac{1}{2} or x + 4 = \frac{1}{2}

x + 4 = - \frac{1}{2} or x + 4 = \frac{1}{2}

x = - \frac{9}{2} or x = - \frac{7}{2}

∣ 2 x - 4 ∣ = 5

∣ x + 3 ∣ + 2.5 = 3

x^{2} - 4 x = 0

∣ 4 x - 15 ∣ = 5

∣ 9 + 2 x ∣ = 3
