I am having some trouble with these questions. Thank you so much for your help

A)

Find an explicit solution of the following initial-value problem (IVP) ixy+1y3 =1, y(~\\/)=1. Also, determine the interval I of definition of the solution found. Find an explicit solution of the following initial-value problem dy + (1 - x)y = xet, y(1) =e. dx Give the largest interval I over which the solution is defined
