4-4|7u-56|=-52

4 - 4 ∣ 7 u - 56 ∣ = - 52

u = 6 or u = 10

Solution steps

4 - 4 ∣ 7 u - 56 ∣ = - 52

Move

4

to the right side

- 4 ∣ 7 u - 56 ∣ = - 56

Divide both sides by

- 4

∣ 7 u - 56 ∣ = 14

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

7 u - 56 = - 14 or 7 u - 56 = 14

7 u - 56 = - 14 or 7 u - 56 = 14

u = 6 or u = 10

∣ x - 4 ∣ = ∣ x + 6 ∣

∣ n + 2 ∣ = 1

∣ 3 x ∣ + 9 = 6

x^{2} - x = 0

12 = ∣ 9 x + 1 ∣ 3
