Cassie has 10 cousins. There is only 1 Jackson cousin, but there are twice as many Lopez cousins as Chen cousins. How many Lopez cousins does she have

Given:

10 cousins

1 Jackson cousin

twice as many Lopez cousin as Chen cousin.

The unknown are the number of Lopez cousin and Chen cousin.

Let x represent the number of Chen cousin. Since Lopez cousin is twice the number of Chen cousin, the Lopez cousin is represented by 2x.

1 + 2x + x = 10

3x = 10 - 1

3x = 9

x = 9/3

x = 3 → Number of Chen cousins

2x → 2 (3) = 6 → Number of Lopez cousins

There is 1 Jackson cousin, 6 Lopez cousins, and 3 Chen cousins. For a total of 10 cousins.
