x= cost of adult ticket
\n" ); document.write( "y= cost of child ticket
\n" ); document.write( "
\n" ); document.write( "8.00 x + 6.00 y = 132.00 .............1
\n" ); document.write( "Total value
\n" ); document.write( "10.00 x + 4.00 y = 144.00 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -4.00
\n" ); document.write( "Multiply (2) by 6.00
\n" ); document.write( "-32.00 x -24.00 y = -528.00
\n" ); document.write( "60.00 x + 24.00 y = 864.00
\n" ); document.write( "Add the two equations
\n" ); document.write( "28.00 x = 336.00
\n" ); document.write( "/ 28.00
\n" ); document.write( "x = 12.00
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "8.00 x + 6.00 y = 132.00
\n" ); document.write( "96.00 + 6.00 y = 132.00
\n" ); document.write( " 6.00 y = 132.00 -96.00
\n" ); document.write( " 6.00 y = 36.00
\n" ); document.write( " y = 6.00
\n" ); document.write( "x= 12 cost of adult ticket $
\n" ); document.write( "y= 6 cost of child ticket $
