⭐️- Frank’s sister’s age is x years
- Frank’s age is 8 years older
1. Frank’s age equation is: x+8
2. After 3 years, the equation changes to: x+11
3. Frank’s sister’s age equation is: x+3
4. Twice means 2
5. The full equation is: x+11 = 2(x+3)
6. x= 5
7. 5+8= 13; Frank is 13 years old and his sister is 5 years old
