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

Decimal Notation

x = - 0.66666 \dots, x = 1.33333 \dots

Solution steps

∣ 3 x - 1 ∣ + 9 = 12

Move

9

to the right side

∣ 3 x - 1 ∣ = 3

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

3 x - 1 = - 3 or 3 x - 1 = 3

3 x - 1 = - 3 or 3 x - 1 = 3

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

∣ a ∣ = - 1, - 8, - 4

3 ∣ y - 6 ∣ + 9 = 45

3 - 2 ∣ 7 x - 7 ∣ = 7

x^{2} - x + 4 = 2

∣ 6 x - 9 ∣ = 3 x - 3
