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:
![3x- 15+(15)= 60+(15)\\3x=75](/tex.php?f=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](/tex.php?f=\frac{3x}{3}=\frac{75}{3}\\\\x=25)
therefore, we can conclude that bea's uncle is 25 years old.
