You can put this solution on YOUR website!
x + 2y = -7
\n" ); document.write( "x = y + 23
\n" ); document.write( "..
\n" ); document.write( "x+2y=-7
\n" ); document.write( "x-y=23
\n" ); document.write( "subtract one from another to eliminate x
\n" ); document.write( "x+2y-x+y=-7-23
\n" ); document.write( "3y=-30
\n" ); document.write( "y=-10
\n" ); document.write( "..
\n" ); document.write( "Plug the value of y in any equation above
\n" ); document.write( "x-(-10)=23
\n" ); document.write( "x+10=23
\n" ); document.write( "x=13
\n" ); document.write( "
\n" );
