A system of equations is shown below.
Equation 1: 21 - y=-8
Equation 2: 2 + 2y = 6
To begin solving the system of equations, Equation 1 is multiplied by a value of 2 to create Equation 3.
Equation 3: 42 – 2y = -16
Equation 2: 2 + 2y = 6
Which procedure could best be used to eliminate one of the variables?
add Equation 2 to Equation 3
subtract Equation 2 from Equation 3
subtract Equation 3 from Equation 2
