each shirt x $
\n" ); document.write( "each tie y $
\n" ); document.write( "
\n" ); document.write( "6 x + 2 y = 88.68 .............1
\n" ); document.write( "4 x + 3 y = 68.27 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -3
\n" ); document.write( "Multiply (2) by 2
\n" ); document.write( "-18 x -6 y = -266.04
\n" ); document.write( "8 x 6 y = 136.54
\n" ); document.write( "Add the two equations
\n" ); document.write( "-10 x = -129.5
\n" ); document.write( "/ -10
\n" ); document.write( "x = 12.95
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "6 x + 2 y = 88.68
\n" ); document.write( "77.7 + 2 y = 88.68
\n" ); document.write( " 2 y = 88.68 -77.7
\n" ); document.write( " 2 y = 10.98
\n" ); document.write( " y = 5.49
\n" ); document.write( "shirt ----$12.95\r
