To solve 10x-35+3ax=5ax-7a, we'll need to assume that a is a constant and that we are to solve for the variable x.  To accomplish this, group all the x terms together on one side and all of the no-x terms on the other:
10x + 3ax - 5ax = -7a + 35
Factoring x out of the left side, we get:
x(10 - 2a) = 7(5 - a).  Dividing both sides by (10 - 2a), we get:
        7(5 - a)
x = ------------ = 7/2
       2(5 - a)
x has the value 7/2.
