(|r+1|)/5 =3

\frac{∣ r + 1 ∣}{5} = 3

r = - 16 or r = 14

Solution steps

\frac{∣ r + 1 ∣}{5} = 3

Multiply both sides by

5

∣ r + 1 ∣ = 15

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

r + 1 = - 15 or r + 1 = 15

r + 1 = - 15 or r + 1 = 15

r = - 16 or r = 14

\frac{1}{2} t - 4 = 1

∣ v - 5 ∣ + 6 = 18

∣ 10 x ∣ = 10

4 = ∣ w - 6 ∣

∣ 2 x + 6 ∣ = 14
