\n" ); document.write( "Equations:
\n" ); document.write( "u = 2t
\n" ); document.write( "10u+t = 10t+u+27
\n" ); document.write( "-----
\n" ); document.write( "Substitute for \"u\" and solve for \"t\":
\n" ); document.write( "10(2t)+t = 10t+(2t) + 27
\n" ); document.write( "21t = 12t+27
\n" ); document.write( "9t = 27
\n" ); document.write( "t = 3
\n" ); document.write( "---
\n" ); document.write( "u = 2t = 6
\n" ); document.write( "---
\n" ); document.write( "Ans: 10t+u = 36
