Ok, let me work on it for a bit, then I'll post and explain, ok?

imstuck · Answer

Ok you have several things going on at the same time here.  You need to separate the dry waste from the wet, then you need to separate the collection times from the processing times, then you need to take into account that you have both men and machine working on this and that the hours they can work are each different.  So let's worry about the men and the machine part because they are after all the ones doing the work.  So we have the men that can work no more than 150 hours, and the machine that can work no more than 200 hours.  The men collect the waste and the machine processes it.  So a system of inequalities looks like this:

imstuck · Answer

The first equation means that it takes 35 hours for the men to collect the dry waste and 42 hours for the men to collect the wet waste.  That cannot equal more than the 150 hours they are allowed to work.

imstuck · Answer

The second equation means that it takes the machine 55 hours to process the dry waste and 63 hours to process the wet waste.  Those added together cannot equal more than the 200 hours the machine is allowed to work.

ok

So you set up that system and answer the question they ask you:  can the men and machines process 3 tons of dry waste and 2 tons of wet waste in a week?  Well let's see!

imstuck · Answer

Doing the math for the first equation tells us that the combined time for man to collect both types of waste is 189 hours, more than the allowed 150.

imstuck · Answer

The second equation tells us that the combined time for machine to process both types of waste is 291.

imstuck · Answer

So it is not possible for them to collect and process 3 tons of dry waste and 2 tons of wet waste in one week.
