∣ 7 x - 1 ∣ = 10

x = - \frac{9}{7} or x = \frac{11}{7}

Decimal Notation

x = - 1.28571 \dots, x = 1.57142 \dots

Solution steps

∣ 7 x - 1 ∣ = 10

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

7 x - 1 = - 10 or 7 x - 1 = 10

7 x - 1 = - 10 or 7 x - 1 = 10

x = - \frac{9}{7} or x = \frac{11}{7}

x^{2} + 4 x + 8

∣ 2 x - 7 ∣ \geq 1

12 = \frac{5}{2} w

5 x + 2 \leq - 18
