0.5 ∣ 2 x + 5 ∣ + 4 = 14

x = - \frac{25}{2} or x = \frac{15}{2}

Decimal Notation

x = - 12.5, x = 7.5

Solution steps

0.5 ∣ 2 x + 5 ∣ + 4 = 14

Multiply both sides by

10

5 ∣ 2 x + 5 ∣ + 40 = 140

Move

40

to the right side

5 ∣ 2 x + 5 ∣ = 100

Divide both sides by

5

∣ 2 x + 5 ∣ = 20

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 x + 5 = - 20 or 2 x + 5 = 20

2 x + 5 = - 20 or 2 x + 5 = 20

x = - \frac{25}{2} or x = \frac{15}{2}

∣ - 6 x - 200 ∣ = 160

2 ∣ v - 4 ∣ = 38

x^{2} - ∣ 2 x - 3 ∣ - 4 = 0

∣ y + 975 ∣ = 5

∣ c + 9 ∣ - 1 = 68
