neceito ayuda en este problema, pasenlo reuelto por favor.

Answer 1

Explicación paso a paso:

$\frac{ - 3(x - 3)}{5} - \frac{7x - 2}{2} = - \frac{2}{10} (x + 8) - 7 \\ \\ \frac{ - 3x + 9}{5} - \frac{7x - 2}{2} = - \frac{1}{5} (x + 8) - 7 \\ \\ \frac{ - 3x + 9}{5} - \frac{7x - 2}{2} = - \frac{1}{5} x - \frac{8}{5} - 7 \\ \\ \frac{ - 3x + 9}{5} - \frac{7x - 2}{2} = - \frac{1}{5} x \frac{ - 8 - 35}{5} \\ \\ \frac{ - 3x + 9}{5} - \frac{7x - 2}{2} = - \frac{1}{5} x - \frac{43}{5} \\ \\ 10 ( \frac{ - 3x + 9}{5} - \frac{7x - 2}{2} ) = 10( - \frac{1}{5} x - \frac{43}{5} ) \\ \\ \frac{ - 30x + 90}{5} - \frac{70x - 20}{2} = - \frac{10}{5} x - \frac{430}{5} \\ \\ (- \frac{30}{5} x + \frac{90}{5} ) - ( \frac{70x}{2} - \frac{20}{2} ) = - 2x - 86 \\ \\ - 6 x+ 18 - (35x - 10) = - 2x - 86 \\ - 6x + 18 - 35x + 10 = - 2x - 86 \\ - 41x + 28 = - 2x - 86 \\ - 41x + 2x = - 86 - 28 \\ - 39x = - 114 \\ x = - 114 \div ( - 39) \\ \\ x = \frac{38}{13}$
