You did not include the choices. However, I answered one that just included them. I've included the possible answers below and then the correct answers.

A multiple of Equation 1.

B. The sum of Equation 1 and Equation 2

C. An equation that replaces only the coefficient of x with the sum of the coefficients of x in Equation 1 and Equation 2.

D. An equation that replaces only the coefficient of y with the sum of the coefficients of y in Equation 1 and Equation 2.

E. The sum of a multiple of Equation 1 and Equation 2.

A, B and E.

Adding and multiplying the terms allow them to keep working. However, you must make sure that each variable is changed each time. Not just one as in C and D.
