Let x be the YOUNGER one and y is the OLDER one:
\n" ); document.write( "y - x = 37
\n" ); document.write( "y + x = 55
\n" ); document.write( "Solve by adding the equations:
\n" ); document.write( "2y = 92
\n" ); document.write( "y = 92/2
\n" ); document.write( "y = 46
\n" ); document.write( "46 -x = 37
\n" ); document.write( "-x = 37 - 46
\n" ); document.write( "-x = -9
\n" ); document.write( "x = 9
\n" ); document.write( "Thus the older friend is 46 years old.
