$\"7x%2B3y=5\"$ -------------------> A
\n" ); document.write( " $\"3x-22y=12\"$ -----------------> B
\n" ); document.write( " $\"2x-y=-1\"$ ------------------> C
\n" ); document.write( " $\"x%2B2y=7\"$ -------------------> D
\n" ); document.write( "In A:
\n" ); document.write( " $\"3y=5-7x\"$ ---> $\"y=%285%2F3%29-%287%2F3%29x\"$
\n" ); document.write( "In B:
\n" ); document.write( " $\"22y=3x-12\"$ ---> $\"cross%2822%29y%2Fcross%2822%29=%283x-12%29%2F22\"$
\n" ); document.write( " $\"y=%283%2F22%29x-%2812%2F22%29\"$ ---> $\"y=%283%2F22%29x-%286%2F11%29\"$
\n" ); document.write( "In C:
\n" ); document.write( " $\"y=2x%2B1\"$
