(4,2) or x=4 and y=2

#### Explanation:

Since you are given the second equation solved in terms of x, you can plug what x equals in for x in the first equation to get rid of the x variable. This would be:
$5 \textcolor{red}{\left(4 y - 4\right)} - 4 y = 12$
You would then distribute and simplify:
$20 y - 20 - 4 y = 12$
$16 y - 20 = 12$
$16 y = 32$
$y = 2$
You then plug this y value back into one of the original equations to find x. Let's use the second equation:
$x = 4 \textcolor{red}{\left(2\right)} - 4$
So $x = 4$
And the overall solution, in coordinate form, would be: (4,2)
