Mathcad Solve Block Problem

Tags:

    I'm having trouble solving for two variables in Mathcad. I'm relatively inexperienced with this software and I'm not sure whether it's the software or my math but anyway i've included screen dumps to highlight the problem. I have tried the Given/Find block in two different ways. The first does not give me an answer as you might notice and the second just crashes every time I try to evaluate 'ans'

    I've only looked at the first image. You need to provide "guess" values for the variables you wish to find in a solve block.
