What is the first step to take when solving this linear system of equations by the addition-subtraction method? 2x + 4y = 3 x + 3y =13 a) solve for y in terms of x b) solve for x in terms of y c) multiply the first equation by ? 2 d) multiply the second equation by ? 2

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
