Question

va rog ex 12.Dau coroana la ala care imi raspunde si imi spune cum a facut.

Answer 1

$\frac{x+1}{x} = \frac{\frac{3}{9} + \frac{27}{99} + \frac{123-1}{99} }{ \frac{45}{10}: \frac{9}{100}+2+ \frac{1}{ \frac{2}{2} + \frac{1}{2} } }$
$\frac{x+1}{x} = \frac{\frac{33+27+122}{99}}{ \frac{45}{10}* \frac{100}{9}+2+ \frac{1}{ \frac{3}{2} } }$
$\frac{x+1}{x} = \frac{\frac{182}{99}}{ 50+2+\frac{2}{3} } }$
$\frac{x+1}{x} = \frac{\frac{182}{99}}{\frac{156+2}{3} } }$
$\frac{x+1}{x} = {\frac{182}{99}}*{\frac{3}{158} } }$
$\frac{x+1}{x} = {\frac{91}{33}}*{\frac{1}{79} } }$
$\frac{x+1}{x} = {\frac{91}{33*79}}$
$\frac{x+1}{x} = {\frac{91}{2607}}$
[tex]91x=2607(x+1) [/tex]
$91x=2607x+2607$
$2516x=-2607$
$x= \frac{-2607}{2516}$
