- 2 ∣ - 7 d + 9 ∣ - 6 = - 12

d = \frac{6}{7} or d = \frac{12}{7}

Decimal Notation

d = 0.85714 \dots, d = 1.71428 \dots

Solution steps

- 2 ∣ - 7 d + 9 ∣ - 6 = - 12

Move

6

to the right side

- 2 ∣ - 7 d + 9 ∣ = - 6

Divide both sides by

- 2

∣ - 7 d + 9 ∣ = 3

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 7 d + 9 = - 3 or - 7 d + 9 = 3

- 7 d + 9 = - 3 or - 7 d + 9 = 3

d = \frac{6}{7} or d = \frac{12}{7}

∣ 6 v - 3 ∣ = 15

∣ 5 v - 10 ∣ = 5

3 ∣ x - 4 ∣ = 12

∣ 5 v - 10 ∣ = 0

3 ∣ x - 4 ∣ = 24
