Answer:

D

Step-by-step explanation:

multiply the second equation by −2

In the addition-subtraction method, the two equations in the system are added or subtracted to create a new equation in one variable. In order for the new equation to have only one variable, the other variable must cancel out.

multiply the second equation by −2:

2x + 4y = 4

−2x − 6y = −26

→ −2y = −22
