    Consider the following relation:


    on the stack.

    Next I put the variable 'L' on stack level 1 and then use symbolic solve > ISOL (or perhaps algebra > ISOL for Hp48). I get


    instead of just 'L=100_yd-2*W'. I get a "+" sign before the "-" sign. Is there some flag setting which is giving me the additional "+" sign?

    PS: It's an example taken from HP Insights vol 2 pag 517.
