Solve the system.
\n" ); document.write( "5x + 5y – 4z = 13
\n" ); document.write( "5x + 3y + z = –3
\n" ); document.write( "3x – 2y – z = –10
\n" ); document.write( "-------------------
\n" ); document.write( "Add eqns 2 & 3
\n" ); document.write( "---
\n" ); document.write( "Multiply the 2nd eqn by 4 and add to the 1st eqn.
\n" ); document.write( "z is eliminated, leaving 2 eqns in x & y.
\n" ); document.write( "Can you do the rest?
\n" ); document.write( "
\n" );
