Answer 1

45

Explanation:

`x` -
`y` = 30 and
`y` = 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
`x` -
`y` = 30 and
`y` = 15.

First step, substitute the
`y` into the equation
`x` - .

So, it would be

`x` - 15 = 30.

Now, we need the value of
`x`.

`x` - 15 = 30

Group the terms together :

`x` - 15 ( +15 ) = 30 ( +15 )

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

So :

`x` = 45.

Wanna check whether my answer's correct?

Substitute
`x` into
`x` - 15 = 30

That would be :

45 - 15 = 30

So is 45 - 15 = 30?

Yep.

So 45 is the answer.

The value of X is 45.

HOPE THIS ANSWER HELPED :)
