Solve e ^-1 = 5-y^2+y for x

  1. Apr 8, 2015 #1
    1. The problem statement, all variables and given/known data
    Solve e x-1 = 5-y2+y for x

    2. Relevant equations
    /

    3. The attempt at a solution
    ln(ex-1)=ln(5-y2+y)
    x-1=ln(5-y2+y)
    x=ln(5-y2+y)+1

    can I go any further ?

    Nope, just mind one thing, you have to include a constraint that 5-y2+y>0 which holds only if y satisfies an inequality regarding its values.

    Btw i just noticed one small "typo", it should be x=ln(..)+1 not -1...
