Answer:
x = 27
Step-by-step explanation:
I'm assuming the equation looks like this:
Here's how to solve for x:
(subtract 5 from both sides)
(Find the GCF of 3 and 9, which is 3. Multiply 2/3 by 3/3. You get 6/9)
(add like terms)
(multiply 9/5 to both sides, which is the same as dividing both sides by 5/9)
x = 27

The graph is a circle, centered at the origin, with radius=4.
We know that we can write the equation of a circle with radius r and center (a,b) as :
.
Thus, substituting (a, b) with (0, 0) and r with 4, we have:
.
The solutions of this equation are all the points forming the circle shown in the picture. The solutions of this equation are still the same even if we multiply both sides of the equation by 2, because rewriting the equation as:
,
we would still have the same roots.
Thus, the equation of the circle can be written as :
.
