Solve an equation for a particular variable using Wolfram Alpha

Question

I want to express variable from equation in WolframAlpha web. I tried several keywords but it didn't work. For example I have equation

$$y=x+z+k,$$

and I want Wolfram to rewrite it for variable $x$, $x=y-z-k$. Is it possible and how?

Answer 1

You can use the following query:

solve(y=x+z+k,x)

Answer 2

To complete my previous comment, this is what you may type to achieve what you asked.

I just copied and pasted your equation in WolphramAlpha, the remaining "syntax" was suggested to me by the usual WA output page ("solution for variable $x$").
