e^x  y = 2 e^x + y = 1 so and for these equations ?
 one year ago

hartnn Group TitleBest ResponseYou've already chosen the best response.0
but if x is imaginary, y must be imaginary also, right ?
 one year ago

jhonyy9 Group TitleBest ResponseYou've already chosen the best response.1
but in this case i think that is very simple us ln to both sides for every two equations and will get the right answers
