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
Answer:
There are 48 students in the science club.
Step-by-step explanation:
Total students: T=84
T=R+S→R+S=84 (eq. 1)
Students in Robotics club: R
Students in science club: S
The science club is 12 more students in the robotics club:
(eq. 2) S=12+R
How many students are in the science club?
S=?
Replacing eq. 2 in eq. 1:
(eq. 1) R+S=84
R+(12+R)=84
R+12+R=84
Adding like terms on the left side of the equation:
2R+12=84
Solving for R: Subtracting 12 both sides of the equation:
2R+12-12=84-12
Subtracting:
2R=72
Dividing both sides of the equation by 2:
2R/2=72/2
Dividing:
R=36
Replacing R by 36 in eq. 2:
(eq. 2) S=12+R
S=12+36
S=48
There are 48 students in the science club.
