point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":
