x = - \frac{7}{8} or x = - \frac{1}{8}

Decimal Notation

x = - 0.875, x = - 0.125

Solution steps

∣ 2 x + 1 ∣ = \frac{3}{4}

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

2 x + 1 = - \frac{3}{4} or 2 x + 1 = \frac{3}{4}

2 x + 1 = - \frac{3}{4} or 2 x + 1 = \frac{3}{4}

x = - \frac{7}{8} or x = - \frac{1}{8}

∣ x - 2 ∣ = 21

3 x - 2 = ∣ x - 2 ∣

∣ 2 x + 3 ∣ = 6 x - 9

∣ x + 3 ∣ = 5 + x

9 ∣ 5 a - 5 ∣ - 10 = 35
