5 ∣ 3 - 12 x ∣ = 20

x = - \frac{1}{12} or x = \frac{7}{12}

Decimal Notation

x = - 0.08333 \dots, x = 0.58333 \dots

Solution steps

5 ∣ 3 - 12 x ∣ = 20

Divide both sides by

5

∣ 3 - 12 x ∣ = 4

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

3 - 12 x = - 4 or 3 - 12 x = 4

3 - 12 x = - 4 or 3 - 12 x = 4

x = - \frac{1}{12} or x = \frac{7}{12}

∣ 2 x - 4 ∣ = - 7

∣ x + 1 ∣ = 4 + 2 x

∣ x - 1 ∣ - 2 \geq = 0

x^{2} + x - 2 = x + 3

17 = 3 ∣ z + 3 ∣ - 4
