Summer Camp Group Division

At a summer camp, the campers are divided into two groups: Group A and Group B. The number of campers in Group A is twice the number of campers in Group B. If the total number of campers is 84, how many campers are in Group A?

Let the number of campers in Group B be denoted as $x$. Therefore, the number of campers in Group A can be represented as $2x$. The total number of campers can be expressed in the equation:

$$x + 2x = 84$$
