∣ - 3 a + 8 ∣ = 11

a = - 1 or a = \frac{19}{3}

Solution steps

∣ - 3 a + 8 ∣ = 11

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 3 a + 8 = - 11 or - 3 a + 8 = 11

- 3 a + 8 = - 11 or - 3 a + 8 = 11

a = - 1 or a = \frac{19}{3}

4 - 4 ∣ 6 - 3 x ∣ = - 16

13 = ∣ 2 b + 12 ∣

4 - 5 ∣ 10 + 5 x ∣ = - 51

∣ b + 3 ∣ = 3

∣ 3 x - 6 ∣ = 12
