2, -4.

#### Explanation:

By first cross-multiplying 7 then trasposing, the eqn. becomes,

a(a+4)-2(a+4)=0, i.e., (a+4)(a-2)=0.

Hence the soln. : a=-4, a=2.

#### Explanation:

As the top values (numerators) are of the same value we could disregard them and simply write

However, I suspect the that question poser is looking for you to use algebraic manipulation. So hear goes!

Invert both sides giving:

Multiply both sides by

But
