You can put this solution on YOUR website!
-x + 8y =-32......1
\n" ); document.write( "3x - y = 27......2
\n" ); document.write( "Multiply (1) by 3
\n" ); document.write( "-3x + 24y = -96....3
\n" ); document.write( " 3x - y = 27.....2
\n" ); document.write( "Add (3) + (2)
\n" ); document.write( " 23y = -69
\n" ); document.write( " y = -3
\n" ); document.write( "Substitute y = -3 into (2)
\n" ); document.write( " 3x - y = 27
\n" ); document.write( " 3x -(-3) = 27
\n" ); document.write( " 3x + 3 = 27
\n" ); document.write( " 3x = 27 - 3
\n" ); document.write( " 3x = 24
\n" ); document.write( " x = 8
\n" ); document.write( "x = 8 y = -3
\n" ); document.write( "Hope this helps.
