1/2t - 1/5v = 5/2
\n" ); document.write( "2/3t + 1/4v = 7/12
\n" ); document.write( "---
\n" ); document.write( "Get rid of those fractions:
\n" ); document.write( "5t - 2v = 25
\n" ); document.write( "8t + 3v = 7
\n" ); document.write( "----
\n" ); document.write( "Multiply 1st by 3
\n" ); document.write( "Multiply 2nd by 2
\n" ); document.write( "----
\n" ); document.write( "15t - 6v = 75
\n" ); document.write( "16t + 6v = 14
\n" ); document.write( "-----
\n" ); document.write( "Add and solve for \"t\":
\n" ); document.write( "31t = 89
\n" ); document.write( "t = 89/31
\n" ); document.write( "----
\n" ); document.write( "solve for \"v\":
\n" ); document.write( "5t - 2v = 25
\n" ); document.write( "5*(89/31) - 2v = 25
\n" ); document.write( "2v = 445/31 - 25
\n" ); document.write( "---
\n" ); document.write( "2v = -330/31
