The sum of tiffany's and amanda's age is 28. tiffany's age is 4 years less than amanda's. how old is each girl

Amanda is 16

Step-by-step explanation:

16-4=12

12+16=28

Tiffany is 10, and Amanda is 18

Step-by-step explanation:

If both of their ages combined is 28, then you divide 28 by 2, since there are two people. That would give you 14. So now you have the equation 14 + 14 = 28. Then you take the first 14 and subtract 4 from it, since one of their ages (Tiffany's) is 4 less than the other. But then you have to add 4 to the other 14, to make the sum of the ages still equal to 28. This would give us 10 + 18 = 28.
