You can put this solution on YOUR website!
$\"6x=3%2A2x\"$ , if you want to try by substitution.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"2x=5-5y\"$
\n" ); document.write( "-
\n" ); document.write( " $\"6x=15-15y\"$
\n" ); document.write( "-
\n" ); document.write( " $\"%2815-15y%29%2B7y=-9\"$ ------the substitution made.
\n" ); document.write( "Solve for y. \n" ); document.write( "
