To find an equation equivalent to \( w = x + y - z \), we can rearrange it to express \( z \) in terms of the other variables.
Starting from the original equation: \[ w = x + y - z \]
We can solve for \( z \) by adding \( z \) to both sides and then subtracting \( w \) from both sides: \[ z = x + y - w \]
So the equivalent equation is: \[ z = x + y - w \]
This matches with the response: z = x + y - w.
