let x be the number of adults and y be the number of children
\n" ); document.write( ":
\n" ); document.write( "(1) x + y = 280
\n" ); document.write( ":
\n" ); document.write( "(2) P60x + P25y = P14,000
\n" ); document.write( ":
\n" ); document.write( "solve equation 1 for x and subsitute in equation 2
\n" ); document.write( ":
\n" ); document.write( "x = 280 - y
\n" ); document.write( ":
\n" ); document.write( "P60(280 - y) +P25y = P14,000
\n" ); document.write( ":
\n" ); document.write( "P16,800 - P60y + p25y = P14,000
\n" ); document.write( ":
\n" ); document.write( "P2,800 -P35y = 0
\n" ); document.write( ":
\n" ); document.write( "p35y = P2,800
\n" ); document.write( ":
\n" ); document.write( "y = P2,800/P35 = 80
\n" ); document.write( ":
