solving non numerical matrix in matlab

38 Views Asked by At

I am trying to solve R1 and R2 on this equation in Matlab. I know that all term are constant except R1 and R2. I am trying to see online tutorial but all of them so far has numerical examples (rather than using letter as constant). I am sure there is tutorial about this on Youtube but I cannot find it because I do not know what is called. can you tell me what this method is called?
