-X+3Y=-1
\n" ); document.write( "-X=-3Y-1
\n" ); document.write( "X=3Y+1 NOW SUBSTITUTE (3Y+1) FOR X AND SOLVE FOR Y
\n" ); document.write( "4(3Y+1)-12Y=5
\n" ); document.write( "12Y+4-12Y=5
\n" ); document.write( "4=5 INDICATES THERE IS NO SOLUTION FOR THESE EQUATIONS.
\n" ); document.write( "
\n" );
