\n" ); document.write( "Tim's age plus Cheryl's age is 80.
\n" ); document.write( "Tim's age plus Greg's age is 98.
\n" ); document.write( "Cheryl's age plus Greg's age is 94. What are their ages?
\n" ); document.write( "

Let Tim's, Cheryl's, and Greg's ages be T, C, and G, respectively
\n" );
document.write( "Then we get: T + C     = 80 ------ eq (i)
\n" );
document.write( "       Also, T     + G = 98 ------ eq (ii)
\n" );
document.write( "       And,      C + G = 94 ------ eq (iii)
\n" );
document.write( "                 C - G = - 18 ---- Subtracting eq (ii) from eq (i) ---- eq (iv)
\n" );
document.write( "                    2C = 76 ------ Adding eqs (iv) & (iii)
\n" );
document.write( "C, or 
\n" );
document.write( "Find Cheryl's and Greg's ages on your own! \n" );
document.write( "

\n" );
