$2/5(5x-1)+3/10(10x-3)=-1/2(x-2)-6/5$

Answer 1

Respuesta:

x = 84/110

Explicación paso a paso:

$\frac{10x}{5} - \frac{2}{5} + \frac{30x}{10} - \frac{9}{10} = - \frac{x}{2} + \frac{1}{2} - \frac{6}{5 } \\ 2x - \frac{4}{10} + 3x - \frac{9}{10} = \frac{ - x}{2} + \frac{1}{2} - \frac{12}{2}$

$5x - \frac{13}{10} = - \frac{x}{2} - \frac{11}{2}$

$\frac{10x}{2} + \frac{x}{2} = - \frac{55}{10} + \frac{13}{10}$

$\frac{11x}{2} = \frac{42}{10}$

$x = (\frac{42}{10}) (\frac{2}{11} )$

x = 84/110
