x = - \frac{43}{5} or x = 7

Solution steps

∣ - 10 x - 8 ∣ - 9 = 69

Move

9

to the right side

∣ - 10 x - 8 ∣ = 78

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 10 x - 8 = - 78 or - 10 x - 8 = 78

- 10 x - 8 = - 78 or - 10 x - 8 = 78

x = - \frac{43}{5} or x = 7

∣ 3 x - 7 ∣ - 7 = xx

∣ 2 x ∣ - 7 = 3

- 3 ∣ 3 x - 8 ∣ + 20 = 2

∣ 9 x - 17 ∣ = 1

3 - x^{2} = ∣ 2 x ∣
