There are total of 84 students in the robotics club and the science club. the science club has 12 more students than the robotics club. how many students are in the science club?

84 divided by 2 is 48
one set of 48-12 is 36
36 students are in the science club

To solve this problem we are going to write Let Statements

Let x = number of people in robotics club
Let x+ 12 = number of people in science club

x + x + 12 = 84
2x + 12 = 84
2x = 72
x = 36

Now let's plug x into the expression for the number of people in science club that was written previously.
(36) + 12 = 36

Therefore, there were 36 people in the science club
