x = - \frac{11}{8} or x = \frac{3}{8}

Solution steps

∣ 8 x + 4 ∣ - 12 = - 5

Move

12

to the right side

∣ 8 x + 4 ∣ = 7

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

8 x + 4 = - 7 or 8 x + 4 = 7

8 x + 4 = - 7 or 8 x + 4 = 7

x = - \frac{11}{8} or x = \frac{3}{8}

∣ 3 u + 12 ∣ = 9

- ∣ 3 + x ∣ = - 2

- ∣ 3 + x ∣ = - 3

∣ 2 x - 4 ∣ + 12 = 0

(2 - ∣ k + 1 ∣) = - 6
