Solution:We rewrite the system:\r
\n" ); document.write( "\n" ); document.write( "\"system%28z=3x%2B3%2C+5x%2B3y=1%2C+7x-2y=-11%29\"The two last equations obtained a linear\r
\n" ); document.write( "\n" ); document.write( "system of two variables which we know to find its solutions.\r
\n" ); document.write( "\n" ); document.write( "\"system%285x%2B3y=1%2C7x-2y=-11%29\",Its solution is: (-31/21,-134/63)\r
\n" ); document.write( "\n" ); document.write( "Substitute to find z=3x+3=3(-31/21)+3=-30/21\r
\n" ); document.write( "\n" ); document.write( "Answer:The solution is the ordered triple (-31/21, -134/63, -30/21).\r
\n" ); document.write( "\n" ); document.write( "Done.
