Baron Reid · Answer 1

Let Marc's age be x. If Jeanine is twice as old as Marc, then her age will be 2x. If their ages added together are 24, then you can create the following equation:

2x + x = 24

3x = 24

x = 8

Remember that x is Marc's age. So if Marc is 8, and Jeanine is twice as old, she will be 16.
