Jam is q years old, while Ismail is p years old.
\n" ); document.write( " The sum of their ages is equal to twice the difference of their ages.
\n" ); document.write( "q + p = 2(q-p)
\n" ); document.write( "q + p = 2q - 2p
\n" ); document.write( "Rearrange to
\n" ); document.write( "p + 2p = 2q - q
\n" ); document.write( "3p = q
\n" ); document.write( " The product of their ages 75.
\n" ); document.write( "q*p = 75
\n" ); document.write( " Find q and p
\n" ); document.write( "replace q with 3p in the above equation
\n" ); document.write( "3p*p = 75
\n" ); document.write( "3p^2 = 75
\n" ); document.write( "divide both sides by 3
\n" ); document.write( "p^2 = 25
\n" ); document.write( "p = $\"sqrt%2825%29\"$
\n" ); document.write( "p = 5 yrs
\n" ); document.write( "then
\n" ); document.write( "q = 3(5)
\n" ); document.write( "q = 15 yrs
\n" ); document.write( ";
\n" ); document.write( ":
\n" ); document.write( "confirm this in the statement
\n" ); document.write( "\"The sum of their ages is equal to twice the difference of their ages.\"
\n" ); document.write( "15 + 5 = 2(15-5) \n" ); document.write( "
