You can put this solution on YOUR website!
IF you mean:
\n" ); document.write( " (8/x) - (3/x)+1 = 5 Then:
\n" ); document.write( "8/x-3/x=5-1
\n" ); document.write( "5/x=4
\n" ); document.write( "4x=5
\n" ); document.write( "x=5/4
\n" ); document.write( "x=1.25 ans.
\n" ); document.write( "Proof;
\n" ); document.write( "8/1.25-3/1.25+1=5
\n" ); document.write( "6.4-2.4+1=5
\n" ); document.write( "4+1=5
\n" ); document.write( "5=5
\n" ); document.write( "OR IF you mean:
\n" ); document.write( "8/x-3/(x+1)=5 Then:
\n" ); document.write( "[8(x+1)-3x]/[x(x+1])=5
\n" ); document.write( "[8x+8-3x]/[x^2+x]=5
\n" ); document.write( "[5x+5]/[x^2+x]=5
\n" ); document.write( "5(x^2+x)=5x+5
\n" ); document.write( "5x^2+5x=5x+5
\n" ); document.write( "5x^2+5x-5x-5=0
\n" ); document.write( "5x^2-5=0
\n" ); document.write( "5(x^2-1)=0
\n" ); document.write( "5(x+1)(x-1)=0 ans.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
