1 = \frac{2 x}{- 2.5 \cdot 2.5}

x = - 3.125 or x = 3.125

Solution steps

1 = \frac{2 x}{- 2.5 \cdot 2.5}

Switch sides

\frac{2 x}{- 2.5 \cdot 2.5} = 1

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

\frac{2 x}{- 2.5 \cdot 2.5} = - 1 or \frac{2 x}{- 2.5 \cdot 2.5} = 1

\frac{2 x}{- 2.5 \cdot 2.5} = - 1 or \frac{2 x}{- 2.5 \cdot 2.5} = 1

x = - 3.125 or x = 3.125

∣ 4 x - 1 ∣ = 5 x + 8

∣ 15 x + 4 ∣ = ∣ - 9 x + 2 ∣

∣ 4 v + 6 ∣ = 2

\frac{2}{5} ∣ 3 d - 4 ∣ = 2 d + 4

∣ x - 2 ∣ + 9 = 13
