Solution steps

∣ 7 - 9 v ∣ - 4 = 52

Move

4

to the right side

∣ 7 - 9 v ∣ = 56

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

7 - 9 v = - 56 or 7 - 9 v = 56

7 - 9 v = - 56 or 7 - 9 v = 56

v = - \frac{49}{9} or v = 7

x^{2} - ∣ x ∣ = 6

\frac{∣ x + 4 ∣}{10} = - 1

7 ∣ x + 2 ∣ + 5 x = 0

- 2 ∣ x - 3 ∣ + 8 = - 4

∣ x ∣ = x^{2} + x - 48
