Plz ! will mark brainliest and 15 points! thx so much : )

find z if:

x+y=z and y-z=x

The answer for x+y=z :

ANSWER: IS x=−y+z

The work is :

Step 1: Add -y to both sides.

x + y + −y = z + −y

Which will give you the x= −y + z

The answer for  y-z=x is :

x= y −z

So all you have to do is ...

Flip the equation

like, y-z=x to x= y −z

So at last the two answers to two equations is x= y −z and x=−y+z

* Hopefully this helps:) And answers your question:)
