Let A = Alex's age and F = Frank's age.
\n" ); document.write( "A = F+6 \"Alex is 6 yrs. older than Frank.\"
\n" ); document.write( "A+F = 50 \"\"The sum of their ages is 50.\" Substitute for A, A = F+6 and solve for F.
\n" ); document.write( "(F+6)+F = 50
\n" ); document.write( "2F+6 = 50
\n" ); document.write( "2F = 44
\n" ); document.write( "F = 22 and A = 22+6 = 28.
\n" ); document.write( "Alex is 28 years old and Frank is 22 years old.
\n" ); document.write( "
