5 ∣ 1 + 4 x ∣ - 15 = 0

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

Solution steps

5 ∣ 1 + 4 x ∣ - 15 = 0

Move

15

to the right side

5 ∣ 1 + 4 x ∣ = 15

Divide both sides by

5

∣ 1 + 4 x ∣ = 3

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

1 + 4 x = - 3 or 1 + 4 x = 3

1 + 4 x = - 3 or 1 + 4 x = 3

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

5 ∣ 2 y - 3 ∣ - 4 = 11

∣ 5 x + 2 ∣ - 6 = 27

2 = ∣ s - 5 ∣

- 3 ∣ x - 7 ∣ + 2 = - 13

∣ w - 7 ∣ = 0
