∣ 3 + 9 x ∣ = 10

x = - \frac{13}{9} or x = \frac{7}{9}

Decimal Notation

x = - 1.44444 \dots, x = 0.77777 \dots

Solution steps

∣ 3 + 9 x ∣ = 10

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

3 + 9 x = - 10 or 3 + 9 x = 10

3 + 9 x = - 10 or 3 + 9 x = 10

x = - \frac{13}{9} or x = \frac{7}{9}

x = 2 x + 5

2 x^{3} + 5 x^{2} - 3 x

u^{2} - 2 u - 15 = 0

(2 x^{5} y^{2})^{3}

∣ a - 6 ∣ = 3
