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
The answer is D.
