Question

Inecuación
2x - 1/5 ≤ - 3/10 . (x-1) + 1/5

Answer 1

$2x - \frac{1}{5} \leq \frac{-3x}{10} + \frac{3}{10} + \frac{1}{5} \\ \\ 2x + \frac{3x}{10} \leq \frac{3}{10} + \frac{1}{5} + \frac{1}{5} \\ \frac{20x + 3x}{10} \leq \frac{3}{10} + \frac{2}{5} \\ \\ \frac{23x}{10} \leq \frac{7}{10}$

23x ≤ 7
    x ≤ 7/23
x∈ <-∞, 7/23]
