|(2x-4)/7 |=2

\frac{2 x - 4}{7} = 2

x = - 5 or x = 9

Solution steps

\frac{2 x - 4}{7} = 2

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

\frac{2 x - 4}{7} = - 2 or \frac{2 x - 4}{7} = 2

\frac{2 x - 4}{7} = - 2 or \frac{2 x - 4}{7} = 2

x = - 5 or x = 9

- 7 + 10 ∣ 6 r - 10 ∣ = 93

20 - ∣ 2 y - 6 ∣ = 10

2 ∣ x ∣ = 3

3 ∣ 16 x + 18 ∣ - 9 = 15

∣ 1 - 4 x ∣ = 1 + x
