What do we know?
Aliyah has 10 pieces of candy
4 children, each with 2 pieces of candy.
If each of 4 children receives 2 pieces of candy, the children have a total of 4 * 2 pieces of candy = x
Take that answer and add it back to the 10 Aliyah has: x + 10.
If you can find x, then you can find x + 10, which is your final answer.
Note: Make sure to actually solve for x, and not just submit "x + 10" as your answer.
