∣ 5 x ∣ = 3

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

Decimal Notation

x = - 0.6, x = 0.6

Solution steps

∣ 5 x ∣ = 3

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

5 x = - 3 or 5 x = 3

5 x = - 3 or 5 x = 3

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

(x + 1)^{2} = x^{2} + 1

x^{2} - 2 x = - \frac{7}{6}

x^{4} + 11 x^{2} + 30

3 ∣ 2 x - 7 ∣ + 5 = 9
