Step-by-step explanation:

- = 30 and = 15

So, I guess you are just messed up with the Xs and Ys.

And I'm not sure what is the 4. ООО  8  80  200 about but here is my guess :

So - = 30 and = 15.

First step, substitute the into the equation - .

So, it would be

- 15 = 30.

Now, we need the value of .

- 15 = 30

Group the terms together :

- 15 ( +15 ) = 30 ( +15 )

So, would be equals to 30 + 15. And in other words, it would be 45.

So :

= 45.

Wanna check whether my answer's correct?

Substitute into - 15 = 30

That would be :

45 - 15 = 30

So is 45 - 15 = 30?

Yep.

So 45 is the answer.
