Let your age be x
\n" ); document.write( "while your brother's age be y
\n" ); document.write( "From the second sentence, you are 5 years older than him. So the equation is:
\n" ); document.write( "x = y + 5. . . . . .(i)
\n" ); document.write( "From the third sentence, the sum of your ages becomes
\n" ); document.write( "x + y = 27. . . . . .(ii)
\n" ); document.write( "Solving simultaneously, using substitution.
\n" ); document.write( "x = 16, y = 11
\n" ); document.write( ".: you are 16yrs old
\n" ); document.write( "
