Okay so, you would just have to simply do one step for this literal equation.
x-b=a
+b +b
x=a+b
You would just have to add b to both sides to cancel out the -b on the left side because you have to isolate x to solve for x. So you add b to both sides, and then the -b gets cancelled out and the right side becomes a+b.
So x = a+b
Hope this helped!

Answer:
A circle whose center is located at point (a, b) having a radius of length r has the equation:
(x -a)² + (y -b)² = r²
(x - -3)^2 + (y -5)^2 = 2^2 =
x^2 +6x + 9 + y^2 -10y +25 =4
