Solve the system of equations by elimination. The answer needs to be in the ordered pair of (x,y,z) form.
\n" ); document.write( "x + y + z = 6 (eq1)
\n" ); document.write( "x + 2y - z = 1 (eq2
\n" ); document.write( "3x - 3y - z = -32 (eq)3
\n" ); document.write( "***
\n" ); document.write( "x + y + z = 6 (eq1)
\n" ); document.write( "x + 2y - z = 1 (eq2)
\n" ); document.write( "add to eliminate z
\n" ); document.write( "2x+3y=7
\n" ); document.write( "..
\n" ); document.write( "x + 2y - z = 1 (eq2)
\n" ); document.write( "3x - 3y - z = -32 (eq3)
\n" ); document.write( "subtract to eliminate z
\n" ); document.write( "-2x+5y=33
\n" ); document.write( "..
\n" ); document.write( "-2x+5y=33
\n" ); document.write( "2x+3y=7
\n" ); document.write( "add to eliminate x
\n" ); document.write( "8y=40
\n" ); document.write( "y=5
\n" ); document.write( "2x=7-3y=7-15=-8
\n" ); document.write( "x=-4
\n" ); document.write( "z=6-x-y=6+4-5=5
\n" ); document.write( "solution:(x,y,z)=(-4,5,5)
\n" ); document.write( " \n" ); document.write( "
\n" );
