2|x+5|=16

2 ∣ x + 5 ∣ = 16

x = - 13 or x = 3

Solution steps

2 ∣ x + 5 ∣ = 16

Divide both sides by

2

∣ x + 5 ∣ = 8

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

x + 5 = - 8 or x + 5 = 8

x + 5 = - 8 or x + 5 = 8

x = - 13 or x = 3

5 - 2 (x^{3}) = 0

∣ 3 + x ∣ = - \frac{1}{2}

\frac{∣ - 7 x + 2 ∣}{5} = 4

\frac{b}{5} = 6

∣ y + 2 ∣ = 8
