\n" ); document.write( "2x+y=12
\n" ); document.write( "y=-2x+12
\n" ); document.write( ".
\n" ); document.write( "y=2x+4 Substitute for y from first equation
\n" ); document.write( "-2x+12=2x+4
\n" ); document.write( "8=4x
\n" ); document.write( "2=x
\n" ); document.write( ".
\n" ); document.write( "y=-2x+12=-2(2)+12=-4+12=8
\n" ); document.write( "ANSWER: The solution is (2,8)
