To find an equation equivalent to \( w = x + y - z \), we can rearrange the original equation to solve for \( z \).
Starting with the given equation:
\[ w = x + y - z \]
We can isolate \( z \) by adding \( z \) to both sides and then subtracting \( w \):
\[ z = x + y - w \]
Therefore, the equivalent equation is:
\[ z = x + y - w \]
This corresponds to the response:
z equals x plus y minus w.
