The ages of sylvana’s three daughters are consecutive even integers. the sum of their ages is 60. write an equation that represents this situation. then, find the age of each daughter.

Let's solve this in two parts, first the equation. Let x represent the ages of the daughters, so the equation is 
x + (x+2) + (x+4) = 60
Next let's calculate the ages.
3x+6=60
3x=54
54/3=18, therefore x=18
x=18
x+2=20
x+4=22
So the ages of the daughters are from youngest to oldest are 18, 20, and 22
