\n" ); document.write( "A solution using two equations with two unknowns, solved by substitution, is of course valid; but it is far more work than necessary for this problem.

\n" ); document.write( "Since one of the pieces of given information is that Sarah is 5 times as old as Sam, it is easy to set up a solution using only one unknown:

\n" ); document.write( "let x = Sam's age
\n" ); document.write( "then 5x = Sarah's age

\n" ); document.write( "2 times Sam's age plus 3 times Sarah's age equals 34:

\n" ); document.write( "\"2%28x%29%2B3%285x%29+=+34\"
\n" ); document.write( "\"17x+=+34\"
\n" ); document.write( "\"x+=+2\"

\n" ); document.write( "ANSWER: Sarah's age is 5x = 10.
