|(+k)/(-2)|=+1

\frac{+ k}{- 2} = + 1

k = - 2 or k = 2

Solution steps

\frac{k}{- 2} = 1

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

\frac{k}{- 2} = - 1 or \frac{k}{- 2} = 1

\frac{k}{- 2} = - 1 or \frac{k}{- 2} = 1

k = - 2 or k = 2

∣ x - 3.5 ∣ = 0

∣ x ∣ + ∣ x - 1 ∣ + ∣ x + 2 ∣ = 3

∣ x + 1 ∣ + ∣ x - 3 ∣ = 3 x - 4

2 x^{2} + ∣ x ∣ - 6 = 0

∣ 1 + 5 x ∣ = - 3
