x= number of adult tickets
\n" ); document.write( "y= number of child tickets
\n" ); document.write( "Total sold
\n" ); document.write( "1 x + 1 y = 42 .............1
\n" ); document.write( "Total value
\n" ); document.write( "5 x + 3 y = 178 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -3
\n" ); document.write( "Multiply (2) by 1
\n" ); document.write( "-3 x -3 y = -126
\n" ); document.write( "5 x + 3 y = 178
\n" ); document.write( "Add the two equations
\n" ); document.write( "2 x = 52
\n" ); document.write( "/ 2
\n" ); document.write( "x = 26
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "1 x + 1 y = 42
\n" ); document.write( "26 + y = 42
\n" ); document.write( " y = 42 -26
\n" ); document.write( " y = 16
\n" ); document.write( " y = 16
\n" ); document.write( "x= 26 number of adult tickets
\n" ); document.write( "y= 16 number of child tickets
