<p>Since the question asks for an expression (not a number), it must be multiple choice. But you didn’t write the answer choices. I would recommend doing this by picking numbers since most students will mess up the algebra.</p>
<p>If you’re asking about a multiple choice question, then you should write the choices. Otherwise you might not get the best solution.</p>
<p>Although I didn’t get this one right in this practice test, I realized that substitution with different values can be used, then I found which equation fitted these values.</p>
