2|x|=5

2 ∣ x ∣ = 5

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

Decimal Notation

x = - 2.5, x = 2.5

Solution steps

2 ∣ x ∣ = 5

Divide both sides by

2

∣ x ∣ = \frac{5}{2}

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

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

∣ 6 y - 18 ∣ = 36

∣ x ∣ = \frac{1}{23}

∣ n + 4 ∣ = 1

∣ x - 3 ∣ = 2 x + 2

∣ x - 2 ∣ + 2 = 5
