Julie just turned 13 years old. In 7 years, her age will be double her brother Pascal's age. How old will Pascal be on Julie's 18th birthday?

8 because if you add seven to thirteen it will be 20. then divide twenty by two because of Pascal. u subtract two from Julie's age and get 18. what u do to one u do to another so u subtract two from ten and get eight

So u have to first do 18 divided by 2 and the answer is 9 her brother will be 9 years old.
