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) and,
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)
