Plz help One real-world problem that is solved by an equation
James has twin sisters (who are the same age, of course). James is 12. If the combined ages of James and his twin sisters equal 42 years, how old are his sisters?

15

Step-by-step explanation:

With the two twins sister in mind we be dividing the difference of James's age with the combined ages

= 30/2

= 15

The age of his two sisters are 15
