\frac{∣ - 7 x + 2 ∣}{5} = 4

x = - \frac{18}{7} or x = \frac{22}{7}

Solution steps

\frac{∣ - 7 x + 2 ∣}{5} = 4

Multiply both sides by

5

∣ - 7 x + 2 ∣ = 20

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 7 x + 2 = - 20 or - 7 x + 2 = 20

- 7 x + 2 = - 20 or - 7 x + 2 = 20

x = - \frac{18}{7} or x = \frac{22}{7}

\frac{b}{5} = 6

∣ y + 2 ∣ = 8

∣ 5 x - 4 ∣ + 5 = 4 x

∣ - 2 b - 10 ∣ = 0

- 10 - 7 ∣ n - 4 ∣ = 74
