Va rog din suflet!!

Answer 1

$\frac{1-4}{3} = \frac{2x+5}{1}$⇒$\frac{1-4}{3} = \frac{2x+5}{1} =\ \textgreater \ 2x+5= \frac{1-4}{3} =\ \textgreater \ 2x+5= \frac{-3}{3} =\ \textgreater \ 2x+5=-1 =\ \textgreater \ 2x[tex] \frac{1-4}{3} = \frac{2x+5}{1} =\ \textgreater \ 2x+5= \frac{1-4}{3} =\ \textgreater \ 2x+5= \frac{-3}{3} =\ \textgreater \ 2x+5=-1 =\ \textgreater \ 2x=-1-5=>2x=-6=>x=-6:2=>x=-3$
