There are a total of 84 students in a robotics club in the science club. The science club is 12 more students in the robotics cl
Anna [14]

Answer:


Step-by-step explanation:

Let the Number of students in the Robotics club be x

So , the number of students in the Science club must be x+12

(Because it is given that the science club have 12 more students.)

Total number of students = 84

So ,

x+(x+12)=84

combining the like terms we get

2x+12=84

Subtract 12 from both sides

2x=72

Divide both sides by 2

x=36

So ,


Number of students in the Robotics club = 36

Number of students in the Science club =36+12 = 48
