4|5+2x|+12=136

4 ∣ 5 + 2 x ∣ + 12 = 136

x = - 18 or x = 13

Solution steps

4 ∣ 5 + 2 x ∣ + 12 = 136

Move

12

to the right side

4 ∣ 5 + 2 x ∣ = 124

Divide both sides by

4

∣ 5 + 2 x ∣ = 31

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

5 + 2 x = - 31 or 5 + 2 x = 31

5 + 2 x = - 31 or 5 + 2 x = 31

x = - 18 or x = 13

8 = ∣ w + 5 ∣

36 - 3 ∣ x ∣ = 18

∣ 3 b + 9 ∣ - 16 = 52

2 ∣ 3 x - 6 ∣ - 2 = 15

∣ - 2 x - 1 ∣ - 3 = 3 x + 16
