2x-3y+z=2 Eqn 1
\n" ); document.write( " x+3y+2z=2 Eqn 2
\n" ); document.write( "3x-y-3z=3 Eqn 3
\n" ); document.write( "-------------------
\n" ); document.write( "2x-3y+z=2 Eqn 1
\n" ); document.write( " x+3y+2z=2 Eqn 2
\n" ); document.write( "----------------------- Add
\n" ); document.write( "3x + 3z = 4 Eqn A
\n" ); document.write( "=====================
\n" ); document.write( " x+3y+2z=2 Eqn 2
\n" ); document.write( "9x-3y-9z=9 Eqn 3 times 3
\n" ); document.write( "----------------------------- Add
\n" ); document.write( "10x - 7z = 11 Eqn B
\n" ); document.write( "30x - 21z = 33 Eqn B times 3
\n" ); document.write( "21x + 21z = 28 Eqn A times 7
\n" ); document.write( "--------------------------------- Add
\n" ); document.write( "51x = 61
\n" ); document.write( "x = 61/51
\n" ); document.write( "==============
\n" ); document.write( "Sub for x in Eqn A or B to find z
\n" ); document.write( "Sub for x and z in any eqn to find y \n" ); document.write( "
