3 ∣ 5 x - 4 ∣ + 21 = 25

x = \frac{8}{15} or x = \frac{16}{15}

Decimal Notation

x = 0.53333 \dots, x = 1.06666 \dots

Solution steps

3 ∣ 5 x - 4 ∣ + 21 = 25

Move

21

to the right side

3 ∣ 5 x - 4 ∣ = 4

Divide both sides by

3

∣ 5 x - 4 ∣ = \frac{4}{3}

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

5 x - 4 = - \frac{4}{3} or 5 x - 4 = \frac{4}{3}

5 x - 4 = - \frac{4}{3} or 5 x - 4 = \frac{4}{3}

x = \frac{8}{15} or x = \frac{16}{15}

X^{2} - 4 ∣ X - 1 ∣ + 5 X + 3 = 0

k^{2} - 5 k = 6

∣ v + 3 ∣ = 5

x^{2} + 7 x - 8 = ∣ x + 1 ∣

ln ∣ y (C) ∣ + C = 3
