Y=4X+3 THEN
\n" ); document.write( "4(4X+3)-20X=-8
\n" ); document.write( "16X+12-20X=-8
\n" ); document.write( "-4X=-8-12
\n" ); document.write( "-4X=-20
\n" ); document.write( "X=-20/-4
\n" ); document.write( "X=5
\n" ); document.write( "Y=4*5+3
\n" ); document.write( "Y=20+3
\n" ); document.write( "Y=23
\n" ); document.write( "PROOF
\n" ); document.write( "4*23-20*5=-8
\n" ); document.write( "92-100=-8
\n" ); document.write( "-8=-8
