x = adult
\n" ); document.write( "y = students
\n" ); document.write( "...
\n" ); document.write( "6x+4.5y=1065
\n" ); document.write( "x+y=210 ==> rearrange as x = 210-y
\n" ); document.write( "...
\n" ); document.write( "Substitution
\n" ); document.write( "6(210-y) + 4.5y = 1065
\n" ); document.write( "1260 - 6y + 4.5y = 1065
\n" ); document.write( "1260 - 1.5y = 1065
\n" ); document.write( "-1.5y = 1065-1260
\n" ); document.write( "-1.5y = -195
\n" ); document.write( "y = 130 student's tickets
\n" ); document.write( "...
\n" ); document.write( "x + 130 = 210
\n" ); document.write( "x = 210 - 130 = 80 adult tickets
