The correct answer is: "The y's because the coefficients are the same."
Further explanation:
we always try to eliminate the variable from the system of equations which involves lesser calculations and complexity.
Assuming that Given equations are:
Equation 1: 82x + 2y = 30
Equation 2: 70x + 2y = 24
we can see that the coefficients of x are very large and different. While the coefficients of y are same. We can only subtract the equations to eliminate y.
Hence,
The correct answer is: "The y's because the coefficients are the same."
