Let x be the cost of adult tickets
\n" ); document.write( "Let y be the cost of children tickets
\n" ); document.write( "x+y=24
\n" ); document.write( "y=24-x (subsitution)
\n" ); document.write( "16x+9y=258
\n" ); document.write( "Subsitute for y:
\n" ); document.write( "16x+9(24-x)=258
\n" ); document.write( "16x-9x=258-216
\n" ); document.write( "7x=42
\n" ); document.write( "x=6
\n" ); document.write( "y=24-6
\n" ); document.write( "y=18
\n" ); document.write( "Hence, about 6 adult tickets were bought and about 18 children tickets were bought.
