1.[tex](89+10-53)xX=0[/tex]
Vom calcula paranteza:
[tex](99-53)xX=0=\ \textgreater \ 46xX=0=\ \textgreater \ 46x=0=\ \textgreater \ X= \frac{0}{46} =0[/tex] (0 impartit la orice numar ne da 0)
2.[tex]8x9x5x1x1xX=16-16=\ \textgreater \ 72x5x1x1xX=0=\ \textgreater \ 360xX=0=\ \textgreater \ [/tex]
[tex]=\ \textgreater \ 360X=0=\ \textgreater \ X= \frac{0}{360} =0[/tex]
