    Is this equation solvable for y?

    Hi all,

    I'm not sure if this question should go in algebra or trigonometry, but...

    I want to know if this equation is solvable for y. x can be negative, but z is always positive (if that makes a difference).

    x = y + e(-1.9 + 3.9×tanh(-(y - 121) ÷ 14)) × (z - 4)(1.9 + 1.4×tanh(-(y -121) ÷ 14))

    I haven't done any math since high school, so please use short words!
    Thank you very much for any help!

    Not analytically, no.

    , thanks anyway! Is it because of the tanh?

    That and that $y$ appears as an exponent as well as a base.
