-|n-9|-10=-15

- ∣ n - 9 ∣ - 10 = - 15

n = 4 or n = 14

Solution steps

- ∣ n - 9 ∣ - 10 = - 15

Move

10

to the right side

- ∣ n - 9 ∣ = - 5

Divide both sides by

- 1

∣ n - 9 ∣ = 5

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

n - 9 = - 5 or n - 9 = 5

n - 9 = - 5 or n - 9 = 5

n = 4 or n = 14

2 x^{2} - x - 8 = 7

15 = 3 - ∣ x + 8 ∣

2 ∣ x + 2 ∣ + 1 = 9

∣ x ∣ = 59.9

∣ 4 p - 5 ∣ = 0
