You can put this solution on YOUR website!
r + 4/3 = r/5
\n" ); document.write( "=> (3r + 4)/3 = r/5
\n" ); document.write( "=> 5(3r + 4) = 3*r
\n" ); document.write( "=> 15r + 20 = 3r
\n" ); document.write( "=> 15r - 3r = -20
\n" ); document.write( "=> 12r = -20
\n" ); document.write( "=> r = -20/12
\n" ); document.write( "=> r = -5/3 \n" ); document.write( "

\n" );
