Given the equation $3x- 15= 60$ , we can say that the<u> </u>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:

$3x- 15+(15)= 60+(15)\\3x=75$

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

$\frac{3x}{3}=\frac{75}{3}\\\\x=25$

Therefore, we can conclude that Bea's uncle is 25 years old.
