The main problem is the r1 and r2 not being explained but I loved it once I knew what those were supposed to be.

Not nice to solve, would be cool, but you don't explain the ratios before the test suite...

Yes, had to use the errors to figure out what the question wanted. Note, it wants s = [ s1 s2 s3] as the output. And don't even try using syms or solve.
