Question

1/5 (×+3)-8/2=×-4/5 ayuda por favor​

Answer 1

Explicación paso a paso:

$\frac{1}{5} (x + 3) - \frac{8}{2} = x - \frac{4}{5} \\ \\ \frac{1}{5} x + \frac{3}{5} - 4 = x - \frac{4}{5} \\ \\ \frac{1}{5} x - x = - \frac{4}{5} - \frac{3}{5} + 4 \\ \\ \frac{1 - 5}{5} x = \frac{ - 4 - 3 + 20}{5} \\ \\ - \frac{4}{5} x = \frac{13}{5} \\ \\ x = \frac{13}{5} \div ( - \frac{4}{5} ) \\ \\ x = - \frac{13}{4} \\ \\ comprobamos \\ \frac{1}{5} ( - \frac{13}{4} + 3) - \frac{8}{2} = - \frac{13}{4} - \frac{4}{5} \\ \\ \frac{1}{5} ( \frac{ - 13 + 12}{4} ) - 4 = \frac{ - 65 - 16}{20} \\ \\ \frac{1}{5} \times ( - \frac{1}{4} ) - 4 = - \frac{81}{20} \\ \\ - \frac{1}{20} - 4 = - \frac{81}{20} \\ \\ \frac{ - 1 - 80}{20} = - \frac{81}{20} \\ \\ - \frac{81}{20} = - \frac{81}{20}$
