Answer:
y = 0.55 or 5 / 9
Step-by-step explanation:
here's the solution :-
=》y + 7 = 19y - 3
=》7 + 3 = 19y - y
=》18y = 10
=》y = 10 ÷ 18
=》y = 5 ÷ 9
=》y = 0.55
I'm not quite sure what you are asking here,
but I got x = 11.

Answer:
its {0,1,2,3,4,5......}
Step-by-step explanation:
Using a system of equations, it is found that <u>since the solution of the system does not involve decimal numbers</u>, it is possible to arrange the books in this way.
For the system, we consider that:
- x is the number of books on the first shelf.
- y is the number of books on the second shelf.
- z is the number of books on the third shelf.
In total, there are 152 books, hence:

The first shelf has 7 fewer books than the second shelf, hence:

Also, it has 11 more books than the third shelf, hence:

Then:


Then, replacing in the first equation:





The number of books in each shelf has to be countable, that is, cannot be decimal.
- Then, <u>since the solution of the system does not involve decimal numbers</u>, it is possible to arrange the books in this way.
