The sum of the ages of Kyle and Meredith is 68 years. 8 years ago, Kyle's age was 3 times Meredith's age. How old is Kyle now?
\n" ); document.write( "

Let Kyle's and Meredith's ages be K and M, respectively
\n" );
document.write( "Then we get: K + M = 68_____M = 68 - K ------ eq (i)
\n" );
document.write( "Also, K - 8 = 3(M - 8) ------ eq (ii)
\n" );
document.write( "K - 8 = 3(68 - K - 8) ------- Substituting 68 - K for M in eq (ii)
\n" );
document.write( "K - 8 = 3(60 - K)
\n" );
document.write( "K - 8 = 180 - 3K
\n" );
document.write( "4K = 188
\n" );
document.write( "Kyle's age, or  \n" );
document.write( "

\n" );
