first let me thank you all for your help. my problem is A,B and C can finish a job in 6 days if B and C work together the job will take 9 days if A and C work together the job will take 8 days in how many days can each man working alone do the job?
\n" ); document.write( "----------------------------
\n" ); document.write( "Let the alone time for each be a, b, and c
\n" ); document.write( "Then their respective rates are 1/a, 1/b, and 1/c
\n" ); document.write( "----------------------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "1/a + 1/b + 1/c = 1/6
\n" ); document.write( "0 + 1/b + 1/c = 1/9
\n" ); document.write( "1/a + 0 + 1/c = 1/8
\n" ); document.write( "----------------------
\n" ); document.write( "Solve the system by any means to get :
\n" ); document.write( "1/a = 1/18
\n" ); document.write( "1/b = 1/24
\n" ); document.write( "1/c = 5/72
\n" ); document.write( "-----------
\n" ); document.write( "Then:
\n" ); document.write( "a would take 18 days
\n" ); document.write( "b would take 24 days
\n" ); document.write( "c would take 72/5 = 14 2/5 days
\n" ); document.write( "==========================
