Answer:

Explanation:
It seems you have started multi-step equations. Understanding multi-step equations is virtually fundamental to higher level mathematics.
Given:

We are multiplying
by the whole expression
, so all you need to do is apply the distributive property. This means multiply
by
and
. When we do that, we then get the following:

We want to solve for the value
, but that means we have to isolate it one one side of the equal sign. Do this by adding
to both sides. We then get:

Now, all we need to do is divide both sides by
to get
by itself. We then get:
