A club puts its members into 5 groups for an activity. After 7 students have to leave early, there are only 3 students left to finish the activity. How many students were in each group?

do i than have to divide 10/5.

5s = 7+3

S = 2.

To find out how many students were in each group, we'll use algebraic equations. Let's assume the number of students in each group is x.

Given that there were originally 5 groups, the total number of students in the clubs is 5x.

After 7 students leave early, there are only 3 students left to finish the activity. This can be expressed as 5x - 7 = 3.

To solve this equation, we'll isolate x. Rearranging the equation, we have 5x = 3 + 7.

Combining like terms, we get 5x = 10.

To isolate x, we'll divide both sides of the equation by 5. This gives us x = 10/5.

Therefore, each group initially had 2 students.
