if a girl is half of her mother,s age and the mother is five years young than the father and their combined number of years is 100,
\n" ); document.write( "what is the age of the girl,the mother and father respectively
\n" ); document.write( ":
\n" ); document.write( "g + m + f = 100
\n" ); document.write( ":
\n" ); document.write( "\"if a girl is half of her mother,s age\"
\n" ); document.write( "g = .5m
\n" ); document.write( ":
\n" ); document.write( "\" and the mother is five years young than the father \"
\n" ); document.write( "m = f - 5
\n" ); document.write( "or
\n" ); document.write( "f = m + 5
\n" ); document.write( ":
\n" ); document.write( "Replace g and f in the 1s equation
\n" ); document.write( ".5m + m + (m+5) = 100
\n" ); document.write( "2.5m = 100 - 5
\n" ); document.write( "2.5m = 95
\n" ); document.write( "m = 95/2.5
\n" ); document.write( "m = 38 yrs is Mom's age
