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":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.

faster, im not sure why but i know it is faster

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
