A system of equations is shown below.

Equation 1: 2x−y=−8
Equation 2: x+2y=6
To begin solving the system of equations, Equation 1 is multiplied by a value of 2 to create Equation 3.

Equation 3: 4x−2y=−16
Equation 2: x+2y=6
Which procedure could best be used to eliminate one of the variables?

Possible Answers:
add Equation 2 to Equation 3

subtract Equation 2 from Equation 3

subtract Equation 3 from Equation 2

multiply Equation 2 by a value of 4
