Adult tickets x numbers
\n" ); document.write( "child tickets y numbers
\n" ); document.write( "
\n" ); document.write( "22 x + 15 y = 228 .............1
\n" ); document.write( "1 x + 1 y = 11 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 1
\n" ); document.write( "Multiply (2) by -15
\n" ); document.write( "22 x 15 y = 228
\n" ); document.write( "-15 x -15 y = -165
\n" ); document.write( "Add the two equations
\n" ); document.write( "7 x = 63
\n" ); document.write( "/ 7
\n" ); document.write( "x = 9.00 OR 9
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "22 x + 15 y = 228
\n" ); document.write( "198 + 15 y = 228
\n" ); document.write( " 15 y = 228-198
\n" ); document.write( " 15 y = 30
\n" ); document.write( " y = 2.00 OR
\n" ); document.write( "Adult tickets 9 numbers
