I do not know where did you take this problem and what is its source.

But one thing I know very firmly:

It is not a way to present a Math problem at this forum as you did.



================

OK, let me express it in more understandable terms.

    If after reading the post by a qualified expert, he still has questions of the type what the condition means,

    then the only place for such a post is in the GARBAGE BOX, and nowhere else.

Maybe you mean:
Find the values of X and Y in A B C D
AB = 2y + 1
2y = AB - 1
y + %28AB-1%29%2F2
:
BC = y + 1
y = BC - 1
:
CD = 7x-3
7x = CD + 3
x = %28CD%2B3%29%2F7
:
DA = 3x
x = %28DA%29%2F3

I agree with the other two tutors that your presentation of the problem is extremely poor.

To start with, a and A, or x and X, can mean different things in the same problem. Don't mix lower and upper case letters when talking about the same thing.

Then your statement of the problem doesn't say that ABCD (not "a b c d") is a rectangle. The topic you chose for presenting your problem was "Rectangles", so I will assume it is; but your statement of the problem should say so.

So then we know that, since opposite sides of a rectangle have the same length,

2y+1 = 7x-3

and

y+1 = 3x

Then the problem tells us to find the values of x and y (not "X and Y").

But here we run into another difficulty with the problem as you present it: the values of x and y turn out to be negative numbers, which makes no sense for the dimensions of a rectangle.
