[tex]35*5-54:a*4=139=\ \textgreater \ \\ 175- \frac{54}{a}*4=139=\ \textgreater \ \\ 175- \frac{216}{a} =139, a \neq 0=\ \textgreater \ \\ - \frac{216}{a} =139-175=\ \textgreater \ \\ - \frac{216}{a} =-36 =\ \textgreater \ \\ -216=-36a=\ \textgreater \ \\ -36a=-216=\ \textgreater \ \\ a=6, a \neq 0=\ \textgreater \ \\ S=[6] \\ Succes [/tex]
175 - 54:ax4 =139 
54 :a x 4 = 175 - 139 
54: a x 4 = 36 
54 : a = 36 :4 
54 : a = 9
a = 54 : 9
a = 6
