\frac{10 x + 1}{2} = \frac{9}{2}

x = - 1 or x = \frac{4}{5}

Decimal Notation

x = - 1, x = 0.8

Solution steps

\frac{10 x + 1}{2} = \frac{9}{2}

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

\frac{10 x + 1}{2} = - \frac{9}{2} or \frac{10 x + 1}{2} = \frac{9}{2}

\frac{10 x + 1}{2} = - \frac{9}{2} or \frac{10 x + 1}{2} = \frac{9}{2}

x = - 1 or x = \frac{4}{5}

x + \frac{1}{3} (x - 3 - \frac{1}{2} (4 - 3 x)) = \frac{2}{3} (1 - \frac{5 x}{2})

\frac{3}{3 15}

∣ 3 x - 4 ∣ = 12

2 x - 5 x = 9

- 8 \cdot (- 10) - 7 \cdot \frac{1}{- 1}
