You can put this solution on YOUR website!
Equation 2 gives you x = 2
\n" ); document.write( "Equation 1 gives you y-2z = 3
\n" ); document.write( "Equation 3 gives you y-z = 6
\n" ); document.write( "subtract
\n" ); document.write( "-z = 3-6
\n" ); document.write( "or z = 3
\n" ); document.write( "y = 9
\n" ); document.write( "check back
\n" ); document.write( "x + y - 2z = 2 + 9 - 6 = 5
\n" ); document.write( "y - z = 9 -3 = 6\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
