I think you've introduced a typo into the Singapore problem. Check the wording carefully.

its on about the solution of the second problem...
I get so mad reading the first problem - any that ask to "Explain" instead of giving the kids actual problems to solve.
The 6th grade Singapore problem is like our 3rd grade enVisionMATH problems, where they call it "Act it out and use reasoning", and I found it difficult to find a method to solve that I could explain to my son, without using a little algebra.
