3 ∣ 2 x + 1 ∣ - 3 = 9

x = - \frac{5}{2} or x = \frac{3}{2}

Decimal

x = - 2.5, x = 1.5

Solution steps

3 ∣ 2 x + 1 ∣ - 3 = 9

Move

3

to the right side

3 ∣ 2 x + 1 ∣ = 12

Divide both sides by

3

∣ 2 x + 1 ∣ = 4

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 x + 1 = - 4 or 2 x + 1 = 4

2 x + 1 = - 4 or 2 x + 1 = 4

x = - \frac{5}{2} or x = \frac{3}{2}

∣ x + 4 ∣ + ∣ x - 2 ∣ = 1

4 = ∣ Y ∣

\frac{7 - x}{6} > 8

x, - x = 3

5 x - 12
