∣ x + 45 ∣ = 100

x = - 145 or x = 55

Solution steps

∣ x + 45 ∣ = 100

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x + 45 = - 100 or x + 45 = 100

x + 45 = - 100 or x + 45 = 100

x = - 145 or x = 55

∣ 3 w - 12 ∣ = 9

- 2 ∣ - b ∣ = - 14

x^{2} - 2 x - x = 0

∣ x ∣ = - x - 1

\frac{∣ 2 x - 10 ∣}{6} = 2
