5 ∣ 2 x - 4 ∣ - 1 = 18

x = \frac{1}{10} or x = \frac{39}{10}

Decimal Notation

x = 0.1, x = 3.9

Solution steps

5 ∣ 2 x - 4 ∣ - 1 = 18

Move

1

to the right side

5 ∣ 2 x - 4 ∣ = 19

Divide both sides by

5

∣ 2 x - 4 ∣ = \frac{19}{5}

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 x - 4 = - \frac{19}{5} or 2 x - 4 = \frac{19}{5}

2 x - 4 = - \frac{19}{5} or 2 x - 4 = \frac{19}{5}

x = \frac{1}{10} or x = \frac{39}{10}

2 ∣ x - 5 ∣ + 7 = 14

1 - ∣ 2 x - 1 ∣ = x

∣ t - 4 ∣ = 1

∣ t - 4 ∣ = 7

8 ∣ b + 70 ∣ = 40
