If this is solving for x and y
\n" ); document.write( "substitute into second
\n" ); document.write( "21(3+y)+8y=-24
\n" ); document.write( "63+21y+8y=-24
\n" ); document.write( "29y=-87
\n" ); document.write( "y=-3
\n" ); document.write( "x=0
\n" ); document.write( "check in second
\n" ); document.write( "0-24=-24
\n" ); document.write( "(0, -3) \n" ); document.write( "
