Answer:
Step-by-step explanation:
step 1
Find the area of the circle with a diameter of 9 units
we know that
The area of a circle is equal to
we have
----> the radius is half the diameter
substitute
step 2
Find the area of a square with a side length of 8 units
we know that
The area of the square is
where
b is the length side of the square
we have
substitute
step 3
Equate the areas
solve for 
Answer:
5x-2y=3
-3x+4y=1
5x-2y=-3x+4y+2
+2y
5x=-3x+6y+2
+3x
8x=6y+2
divide by 2
4x=3y+1
-3y+4x=1
wait so that means that -3x+4y=-3y+4x so that means that both x and y are equal so lets just say their the same
-3x+4x=1
x=1
y=1
Hope This Helps!!!
