A system of equations is shown below.
2x+y=9 and x+3y=-13
Which sequence of operations would produce the correct x- or y-value of the solution to this system of equations?
A) multiply the second equation by –1 and add the result to the first equation to eliminate x and solve for y
B) multiply the first equation by 3 and add the result to the second equation to eliminate y and solve for x
C) multiply the first equation by –3 and add the result to the second equation to eliminate y and solve for x
D) multiply the second equation by and add the result to the first equation to eliminate the constant and solve for x and y
