\frac{8}{7} ∣ x ∣ = 3

x = - \frac{21}{8} or x = \frac{21}{8}

Decimal Notation

x = - 2.625, x = 2.625

Solution steps

\frac{8}{7} ∣ x ∣ = 3

Multiply both sides by

7

8 ∣ x ∣ = 21

Divide both sides by

8

∣ x ∣ = \frac{21}{8}

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x = - \frac{21}{8} or x = \frac{21}{8}

0 = s^{2} - 10 s + 34

10 + 3 (- 9 n + 1) > - 2 n - 2 + 4

n + 1 = 4 (n - 8)

9 u - 14 \leq 6 u - 2

x - 8 (2 + x) < 3 - x + 4
