∣ - 7 u - 5 ∣ = 5

u = - \frac{10}{7} or u = 0

Decimal Notation

u = - 1.42857 \dots, u = 0

Solution steps

∣ - 7 u - 5 ∣ = 5

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 7 u - 5 = - 5 or - 7 u - 5 = 5

- 7 u - 5 = - 5 or - 7 u - 5 = 5

u = - \frac{10}{7} or u = 0

∣ a + 2 ∣ + 9 = 6

∣ 2 x + 1 ∣ = 5 x

- 2 = - ∣ z + 3 ∣ + 3

∣ 3 x - 7 ∣ = 4

∣ 2 x + 1 ∣ = 3 x
