Answer:
((8-2)÷2)+ 2=5 Bob is 5
Explanation:
together they are 8 years old but Bob is 2 years older, so first subtract 2 which is equal to 6. Then divide 6 by 2 because there are two of them (Bob and Alice) which is equal to 3 which is Alices age, while bob is 2 years older, which means 3+2=5. To check you can add 3+5=8
