\n" ); document.write( "Substitution:
\n" ); document.write( " $\"X=2y-3\"$ .......eq.1
\n" ); document.write( " $\"X=2y%2B4\"$ . .....eq.2
\n" ); document.write( "__________________________substitute $\"x\"$ from eq.1 into eq.2\r
\n" ); document.write( "\n" ); document.write( " $\"2y-3=2y%2B4\"$ . .....eq.2...........solve for $\"y\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"2y-2y=3%2B4\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"0=7\"$ .... $\"y\"$ cancels, so there is no solution, lines are parallel\r
