x = - \frac{18}{7} or x = \frac{8}{7}

Decimal Notation

x = - 2.57142 \dots, x = 1.14285 \dots

Solution steps

∣ 5 + 7 x ∣ = 13

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

5 + 7 x = - 13 or 5 + 7 x = 13

5 + 7 x = - 13 or 5 + 7 x = 13

x = - \frac{18}{7} or x = \frac{8}{7}

∣ y ∣ - 4 = 13

∣ 3 u - 54 ∣ = 12

∣ z + 2 ∣ = - 8

∣ 3 x - 5 ∣ - 3 = 3

x^{2} + 6 x + 5 = 0
