2|2h+2|-7=5

2 ∣ 2 h + 2 ∣ - 7 = 5

h = - 4 or h = 2

Solution steps

2 ∣ 2 h + 2 ∣ - 7 = 5

Move

7

to the right side

2 ∣ 2 h + 2 ∣ = 12

Divide both sides by

2

∣ 2 h + 2 ∣ = 6

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 h + 2 = - 6 or 2 h + 2 = 6

2 h + 2 = - 6 or 2 h + 2 = 6

h = - 4 or h = 2

∣ x - 7 ∣ = 20

∣ 10 + 8 p ∣ = 90

2 ∣ x - 3 ∣ + x = 4 x - 4

4 ∣ - p - 9 ∣ - 7 = 45

∣ x - 5 ∣ = 5 x + 7
