General equation of a circle is (x+a)^2 + (y+b)^2 = radius ^2
a and b are the centre and you put in the inverse so as x=-4, a=-4. same for b as the y-coordinate is positive, it becomes negative
the last part is the radius of the circles squared so just 7^2 = 49 !

we have to solve for x , solving for x means , we have to isolate x one one side , by shifting all other variables to other side
So

Multiply both sides by 2
2A = h(x+y)
Divide both sides by h
2A/h = x+y
Subtract y from both sides
