$1 -\frac{2x}{3} = \frac{14}{19} - x\\\\x -\frac{5}{2} = 10\\\\\frac{x}{5} +2 = \frac{x}{3} -3$

Answer 1

Explicación paso a paso:

$1 - \frac{2x}{3} = \frac{14}{19} - x \\ - \frac{2x}{3} + x = \frac{14}{19} - 1 \\ \frac{ - 2x + 3x}{3} = \frac{14 - 19}{19} \\ \frac{x}{3} = - \frac{5}{19} \\ 19x = - 15 \\ x = - \frac{15}{19}$

$x - \frac{5}{2} = 10 \\ x = 10 + \frac{5}{2} \\ x = \frac{20 + 5}{2} \\ x = \frac{25}{2}$

$\frac{x}{5} + 2 = \frac{x}{3} - 3 \\ \frac{x + 10}{5} = \frac{x - 9}{3} \\ 3x + 30 = 5x - 45 \\ 30 + 45 = 5x - 3x \\ 75 = 2x \\ \frac{75}{2} = x$
