    3 variables(constants) with 3 equations derived from calculus.

    I've tried multiple ways yet still cant find the write combination to solveing for x y and z, they are known as constant.

    5.3 = ( x-y*e^(-z) ) / z

    7.7 = ( x-y*e^(-3z) ) / z

    8.95 = ( x-y*e^(-5z) ) / z

    I apologize if this post is in the wrong topic and would gladly delete this and repost it in the right topic if suggested.

    Are you expecting real-valued solutions? WolframAlpha finds only complex solutions:

    5.3=(x-y*e^(-z))/z, 7.7=(x-y*e^(-3z))/z, 8.95=(x-y*e^(-5z))/z - Wolfram|Alpha
