∣ 12 - 6 x ∣ = 3

x = \frac{3}{2} or x = \frac{5}{2}

Solution steps

∣ 12 - 6 x ∣ = 3

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

12 - 6 x = - 3 or 12 - 6 x = 3

12 - 6 x = - 3 or 12 - 6 x = 3

x = \frac{3}{2} or x = \frac{5}{2}

10 + 3 ∣ - 2 R ∣ = 22

10 ∣ 5 b - 4 ∣ + 6 = 16

∣ 3 - 7 x ∣ = 3

∣ 3 y + 6 ∣ - 40 = - 13

∣ 4 x - 12 ∣ = 4
