2 ∣ - 2 x + 5 ∣ = 4

x = \frac{3}{2} or x = \frac{7}{2}

Decimal Notation

x = 1.5, x = 3.5

Solution steps

2 ∣ - 2 x + 5 ∣ = 4

Divide both sides by

2

∣ - 2 x + 5 ∣ = 2

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

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

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

x = \frac{3}{2} or x = \frac{7}{2}

\frac{3 - x}{2} = - 5

∣ 3 x + 5 ∣ = 0

∣ x + 1 ∣ + ∣ x - 2 ∣ = 3 x - 4

∣ 4 - 2 x ∣ + ∣ x + 7 ∣ = 30

a, ∣ a - b ∣ = \frac{∣ b ∣}{2}
