Adult x Tickets
\n" ); document.write( "child y Tickets
\n" ); document.write( "
\n" ); document.write( "1 x + 1 y = 118 .............1
\n" ); document.write( "9 x + 7 y = 1022 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -7
\n" ); document.write( "Multiply (2) by 1
\n" ); document.write( "-7 x -7 y = -826
\n" ); document.write( "9 x 7 y = 1022
\n" ); document.write( "Add the two equations
\n" ); document.write( "2 x = 196
\n" ); document.write( "/ 2
\n" ); document.write( "x = 98
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "1 x + 1 y = 118
\n" ); document.write( "98 + 1 y = 118
\n" ); document.write( " 1 y = 118 -98
\n" ); document.write( " 1 y = 20
\n" ); document.write( " y = 20
