ayudaaaa es examen :(


la resolución porfis :(((((​

Answer 1

Explicación paso a paso:

$\frac{2}{5} (x - 1) + \frac{3}{4} (x - 2) < 6 \\ \frac{2}{5} x - \frac{2}{5} + \frac{3}{4} x - \frac{3}{2} < 6 \\ ( \frac{3}{4} x + \frac{2}{5} x) - ( \frac{2}{5} + \frac{3}{2} ) < 6 \\ \frac{15x + 8x}{20} - ( \frac{4 + 15}{10} ) < 6 \\ \frac{23}{20} x - \frac{19}{10} < 6 \\ \frac{23}{20} x < 6 + \frac{19}{10} \\ \frac{23}{20} x < \frac{60 + 19}{10} \\ \frac{23}{20} x < \frac{79}{10 } \\ 230x < 1580 \\ x < \frac{1580}{230} \\ x < \frac{158}{23}$
