Question

aflati modulul lui 4,5- /x+1/=x

Answer 1

$1) \frac{45}{10} - ( x+1) = x \\ \frac{45}{10} -x -1 = x \\ \frac{45}{10} -1 =2x \\ \\ \frac{45}{10} - \frac{10}{10} =2x \\ \\ \frac{35}{10} =2x \\ \\ x= \frac{35}{20} \\ \\ x= \frac{7}{4} \\ \\ 2) \frac{45}{10} - ( -x-1)=x \\ \\ \frac{45}{10} +x+1 =x =\ \textgreater \ x=0$
