Two machines

The first machine can produce parts in 24 hours, the second in 16 hours. The first started working in the morning at 6:00 pm. Second at 10:00 o'clock. At what hour were all parts made?

Result

x = 18:00 hh:mm Wrong answer

Solution:

 (t−6.00)/24+(t−10.00)/16=1  5t=90  t=18  x=t=18=18:00  hh:mm  \ \\ (t-6.00)/24 + (t-10.00)/16 = 1 \ \\ \ \\ 5t = 90 \ \\ \ \\ t = 18 \ \\ \ \\ x = t = 18 = 18:00 \ \text { hh:mm }
