s = the son's age
\n" ); document.write( "f = father's age
\n" ); document.write( "g = grandfather's age
\n" ); document.write( ":
\n" ); document.write( "write an equation for each statement. Arrange equations to be in terms of f
\n" ); document.write( ":
\n" ); document.write( " Baichung's father is 26 years younger than Baichung's grandfather
\n" ); document.write( "g = f + 26
\n" ); document.write( " and 29 years more than Baichung.
\n" ); document.write( "s = f - 29
\n" ); document.write( " The sum of all the three ages is 135.
\n" ); document.write( "s + f + g = 135
\n" ); document.write( "Replace g with (f+26) and replace s with (f-29)
\n" ); document.write( "(f-29) + f + (f+26)
\n" ); document.write( "3f - 3 = 135
\n" ); document.write( "3f = 138
\n" ); document.write( "f = 138/3
\n" ); document.write( "f = 46 yrs is father's age
\n" ); document.write( "then
\n" ); document.write( "46 + 26 = 72 yrs is grandfather's age
\n" ); document.write( "and
\n" ); document.write( "46 - 29 = 17 yrs is son's age
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Confirm this, see if it all adds up
\n" ); document.write( "17 + 46 + 72 = 135
\n" ); document.write( " What is the age of each one of them? \n" ); document.write( "
\n" );
