Answer:

Explanation:
We have:

Since we already have a variable value (
) in the second equation, it would be easiest to substitute the value for
in the first equation:

Distribute
into
:

Combine like terms:

Add
to both sides of the equation:

Divide by the coefficient of
, which is
:

_
Now that we have our
value, we can substitute that in to the second equation to find our
value:

Multiply:
