This is correct, you first break out X and replace it by 1's were X is alone.

Since you want to isolate X you divide both sides X(1-C) = (a + b + d + e + f) and can thus cross out (1-C) on the left side which then leaves X alone. And much correctly, as already stated, on your right you get (a + b + d - e + f)/(1-C).
Not very hard, but long time ago and memory might not always serve well.
