You could setup a solve block to solve the two equations. However, it seems you have an error in your formulas, see below.

Put the two equations in an array and choose 'solve' from the symbolics menu and supply a,b as the variables to solve for.\

I replaced the (assumed)  knowns in your equations with other constants and solved.

If you don't have a symbolics menu in Prime, you're using the Express version.

You should be able to take it from my solution.

Success!

But you should be able to use my solution.

Note that my A is your first two equation parts between brackets summed.

My B is your Cc+x1/2

My C is your x1

etc.

Success!

But his units are inconsistent. Shouldn't a and b have the same units?

It is the first half of the equation which is the issue.

A.f_r has the units m^2. The second of the equation has the unit m^2.

Yes, they should, because they're added.

But for my, more general, solution that shouldn't make a difference.

Just plug in the right substitutions, and bingo.

Success!
