|(x-1)/2 |=7

\frac{x - 1}{2} = 7

x = - 13 or x = 15

Solution steps

\frac{x - 1}{2} = 7

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

\frac{x - 1}{2} = - 7 or \frac{x - 1}{2} = 7

\frac{x - 1}{2} = - 7 or \frac{x - 1}{2} = 7

x = - 13 or x = 15

∣ 8 x - 1 ∣ = 9

2 ∣ 2 x - 3 ∣ = \frac{5}{2}

x, - f = ∣ x ∣ + 9

a, ∣ a + b ∣ = 4

∣ 5 x + 4 ∣ = 4
