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!
