\n" ); document.write( "With formal algebra....

\n" ); document.write( "Let x = Lin's age
\n" ); document.write( "Then 2x+5 = Mary's age

\n" ); document.write( "The sum of their ages is 32:

\n" ); document.write( " $\"%28x%29%2B%282x%2B5%29+=+32\"$

\n" ); document.write( "I'll let you do the algebra to solve the problem.

\n" ); document.write( "Here is an informal solution method that uses very nearly the same steps as the formal algebraic solution, but without the form algebra.

\n" ); document.write( "(1) Subtract 5 from Mary's age. Now she is twice Lin's ages, and the sum of their ages is 32-5 = 27.
\n" ); document.write( "(2) Mary twice as old as Lin, and the sum of their ages 27, makes Lin 9 and Mary 18.
\n" ); document.write( "(3) Add back on the 5 years you subtracted from Mary's age.

\n" ); document.write( "ANSWER: Lin is 9 and Mary is 18+5 = 23. \n" ); document.write( "

\n" );
