5 + 2 ∣ 2 x + 4 ∣ = 99

x = - \frac{51}{2} or x = \frac{43}{2}

Decimal Notation

x = - 25.5, x = 21.5

Solution steps

5 + 2 ∣ 2 x + 4 ∣ = 99

Move

5

to the right side

2 ∣ 2 x + 4 ∣ = 94

Divide both sides by

2

∣ 2 x + 4 ∣ = 47

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 x + 4 = - 47 or 2 x + 4 = 47

2 x + 4 = - 47 or 2 x + 4 = 47

x = - \frac{51}{2} or x = \frac{43}{2}

∣ x + 4 ∣ + 8 = 5

- 3 ∣ 5 x + 1 ∣ + 4 = 4

∣ u ∣ = 25

∣ u ∣ = 16

- 3 + 10 ∣ n - 10 ∣ = 7
