∣ 3 x + 7 ∣ = 5

x = - 4 or x = - \frac{2}{3}

Decimal

x = - 4, x = - 0.66666 \dots

Solution steps

∣ 3 x + 7 ∣ = 5

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

3 x + 7 = - 5 or 3 x + 7 = 5

3 x + 7 = - 5 or 3 x + 7 = 5

x = - 4 or x = - \frac{2}{3}

9 x^{2} - 6 x + 1 = 0

\frac{1}{a} - 1

(\frac{27}{125})^{- \frac{2}{3}}

3 x^{2} + 6 x - 72

- \frac{4}{x + 5} < 0
