- 2 ∣ 7 - 9 x ∣ + 7 = - 15

x = - \frac{4}{9} or x = 2

Solution steps

- 2 ∣ 7 - 9 x ∣ + 7 = - 15

Move

7

to the right side

- 2 ∣ 7 - 9 x ∣ = - 22

Divide both sides by

- 2

∣ 7 - 9 x ∣ = 11

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

7 - 9 x = - 11 or 7 - 9 x = 11

7 - 9 x = - 11 or 7 - 9 x = 11

x = - \frac{4}{9} or x = 2

5 - 3 ∣ 5 x + 11 ∣ = - 19

4 ∣ 4 - 2 n ∣ - 3 = 93

∣ u - 8 ∣ = - \frac{1}{3}

∣ 3 x + 1 ∣ - 3 = 7

10 = ∣ - 7 x - 1 ∣ 5
