-10.3 + y = 5.2
First, regroup the terms. / Your problem should look like:
Second, add 10.3 to both sides. / Your problem should look like:
Third, add 5.2 + 10.3 to get 15.5 / Your problem should look like:

Answer:
y = 15.5 (D)
//You can substitute some values in to find out, for example (1, -5) and (5, -5) are good.
Using this method, you can deduce that it would be A
I assume you mean
, and not
, since this doesn't satisfy the ODE.
Assume a second solution of the form
, where
is a function of
. Then


Substituting into the ODE gives







where we omit the second term because it's already accounted for by
.
