If 2a = -10, that means a = -5 Because 2(-5) makes -10.
Thus, -6(-5) = 30 #
Therefore, -6a = 30
So with this, you'll be using a proportion to solve it. And here's what your equation will look like:

Firstly, you'll need to cross-multiply. Your equation will look like this: 
For this, all you need to do is square root, and your answer is
, however this answer can be simplified further.

In short, your answer is
