Can someone help me out? I have two linear equations and two unknown variables need to solve for Q1 and Q2.

Is that really all you have? From my A Level experience, you cannot solve find two unknown variables from one equation.

Is there any more information on Q1 or Q2? Or do you need to solve for Q1 in terms of Q2?

your title is a lie. Where's the second linear equation? I only see one.

That's what I thought! I guessed maybe they got confused.
