\frac{∣ k + 7 ∣}{7} = 2

k = - 21 or k = 7

Solution steps

\frac{∣ k + 7 ∣}{7} = 2

Multiply both sides by

7

∣ k + 7 ∣ = 14

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

k + 7 = - 14 or k + 7 = 14

k + 7 = - 14 or k + 7 = 14

k = - 21 or k = 7

3 ∣ x + 3 ∣ - 6 = 0

∣ x + 2 ∣ = 3 x - 1

∣ y + 3 ∣ = 1

- 7 + ∣ - 9 k ∣ = 2

3.5 ∣ 6 x - 2 ∣ = 3.5
