x = \frac{2}{5} or x = \frac{8}{5}

Decimal Notation

x = 0.4, x = 1.6

Solution steps

∣ 5 - 5 x ∣ = 3

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

5 - 5 x = - 3 or 5 - 5 x = 3

5 - 5 x = - 3 or 5 - 5 x = 3

x = \frac{2}{5} or x = \frac{8}{5}

∣ 2 t - 4 ∣ = t - 3

0 = ∣ 2 x - 5 ∣ - 1

∣ 4 - 5 x ∣ + 3 - 2 x = 8

x, - f = ∣ x ∣ + 4

x, - f = ∣ x ∣ + 7
