-|-2+(-a)|+90=-7

- ∣ - 2 + (- a) ∣ + 90 = - 7

a = - 99 or a = 95

Solution steps

- ∣ - 2 - a ∣ + 90 = - 7

Move

90

to the right side

- ∣ - 2 - a ∣ = - 97

Divide both sides by

- 1

∣ - 2 - a ∣ = 97

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

- 2 - a = - 97 or - 2 - a = 97

- 2 - a = - 97 or - 2 - a = 97

a = - 99 or a = 95

x^{2} - 6 x - ∣ 5 x - 15 ∣ - 5 = 0

∣ x + 8 ∣ = 3.5

3 ∣ 3 - x ∣ - 4 ∣ 2 x + 1 ∣ = 2

∣ x ∣ + ∣ x + 1 ∣ + ∣ x + 2 ∣ = 3

∣ x - 2 ∣ + ∣ x ∣ = x^{2} - 2 x
