Begin by subtracting 1/8 from both sides to get

and get a common denominator of 8 on the right:

. Now simplify and cross-multiply: 39x = -16 andx = -16/39
Answer:
The center of the circle is

Step-by-step explanation:
Let the equation of the circle be
, where (-a,-b) is the center of this circle.
The points lying the circle must satisfy the equation of this circle.
A(0,0)
We substitute this point to get;


B(-3,0)



But c=0


C(1,2)



Put the value of 'a' and 'c' to find 'b'




b=-2
Hence the center of the circle is

Just replace a with 4 and b with 2 and your equation looks like
3.14 (4×2+4×2)
solve within the parenthesis first
3.14 (8+8)
3.14 (16) =50.24
6.75 + 3x/8 = 13.25
3x/8 =13.25 - 6.75
3x/8 = 6.5
3X = 6.5 x 8
3x = 52
x= 52/3
So your answer would be 52/3 :)
