two equations, two unknowns, known quantities not being used

I am trying to use the Solve Block, but it is apparently just spitting my guesses back out as the solution. It is not taking into acount the known values. I haven't used MathCAD since ~2007, so I'm frustrated by Prime 3.0. the known values are the Droad....R. The guesses were Smc, and mu

I've tried drastically changing the known quantities, only to see no change in the output. I also tried moving the known quantities outside the Solve Block. Am I using the wrong "="sign ?

I back-checking someone else's work(and relearning some MathCAD) and I know what values they obtained using a similar method.

Please don't attach pictures - attach your worksheet when asking.

You have to use Find(Smc,mu)= at the end of your solve block. You may assign the result to the vector [Smc; mu] to be able to use the results in further calculations.

Have a look at the attached. You has missing a multiplication sign after g.
