\n" ); document.write( "2x+2y=8
\n" ); document.write( "4x+2y=4 Subtract this from above
\n" ); document.write( "-2x=4
\n" ); document.write( "x=-2
\n" ); document.write( "ANSWER 1: x=-2... Back solve using this x value.
\n" ); document.write( "2x+2y=8
\n" ); document.write( "2(-2)+2y=8
\n" ); document.write( "-4+2y=8
\n" ); document.write( "2y=12
\n" ); document.write( "y=6
\n" ); document.write( "ANSWER 2: y=6
\n" ); document.write( "CHECK:(use equation not used to back solve)
\n" ); document.write( "4x+2y=4
\n" ); document.write( "4(-2)+2(6)=4
\n" ); document.write( "-8+12=4
\n" ); document.write( "4=4
\n" ); document.write( " \n" ); document.write( "
