    Change of variables - Differential Equations problem

    Hi

    Can someone please help me with the following problem.

    If:

    y'= (x+2y+5)/(2x+4y-3)

    How do I solve this by expressing the final solution without a log function?

    I would really appreciate a step by step explanation. Many thanks in advance.

    Hey zzizi.

    Can you first get rid of the constants (i.e the 5 and -3) by introducing a suitable transformation?
