First, let's expand the right side. Now our equation is
Now, we gather all the terms with x in it on the left side, and the numbers without x on the right. We get:
And then we can make this
We divide both sides by 12 to get x on its own, so x = 13/12 or 1.08

Answer: (14, 5)
===========================================================
Explanation:
Translating 5 units to the right means x becomes x+5. Whatever the x coordinate is, we add on 5.
Translating 4 units down means we go from y to y-4.
Overall, the point (x,y) becomes (x+5, y-4).
We can write the compact notation
So for the specific point given, we can say:
The point (9,9) shifts to (14, 5)
