Answer:
B) Subtract the bottom equation from the top equation
C) Add the equations.
Step-by-step explanation:
We have to eliminate a variable in the system of equations
6x + 5y = 1 .......... (1) and
6x - 5y = 7 ........... (2)
Since the y-term on both the equations are the same but opposite in sign, therefore the strategy to eliminate y variable from the system of equations (1) and (2) is to add the equations. (Answer)
Again, the x-terms are the same and with a similar sign, therefore, by subtracting the bottom equation from the top equation we can also eliminate the x-variable. (Answer)

Step-by-step explanation:
B= votes Billy got
K = votes Keeton got
B = 3K
B+K =20
Substitute the first equation into the second equation
3K + K =20
Combine like terms
4K =20
Divide both sides by 4
4K/4 = 20/4
K =5
