Question

ayuda con estas dos ecuaciones: -3/4× - 2/8 = -1/4 y con este: 6/2 x + 2/9 = -1/5

Answer 1

$- \frac{3}{4} x - \frac{2}{8}= - \frac{1}{4}$
$- \frac{3}{4} x = - \frac{1}{4} + \frac{2}{8}$
$- \frac{3}{4} x = 0$
$x = 0* \frac{3}{4}$
$x=0$

$\frac{6}{2} x + \frac{2}{9}= - \frac{1}{5}$
$\frac{6}{2} x = - \frac{1}{5}- \frac{2}{9}$
$\frac{6}{2} x = \frac{-9-10}{45}$
$\frac{6}{2} x = -\frac{19}{45}$

$x = \frac{ -\frac{19}{45}}{\frac{6}{2} }$

$x= -\frac{38}{270} =\ \textgreater \ - \frac{19}{135}$
