∣ - 3 x - 7 ∣ - 12 = 9

x = - \frac{28}{3} or x = \frac{14}{3}

Decimal Notation

x = - 9.33333 \dots, x = 4.66666 \dots

Solution steps

∣ - 3 x - 7 ∣ - 12 = 9

Move

12

to the right side

∣ - 3 x - 7 ∣ = 21

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 3 x - 7 = - 21 or - 3 x - 7 = 21

- 3 x - 7 = - 21 or - 3 x - 7 = 21

x = - \frac{28}{3} or x = \frac{14}{3}

x^{2} - 6 x = 2 ∣ x - 3 ∣ + 6

2 ∣ x + 8 ∣ = 14 x

- 4 ∣ w - 16 ∣ + 9 = - 39

1 - 6 ∣ 28 - 4 n ∣ = - 95

∣ 5 - 3 x ∣ + 9 = 13 x + 8
