Solve the system of equations by the substitution method.
victus00 [196]

Answer:

Step-by-step explanation:

Are you certain you wrote the question accurately?—because none of the choices is correct.

rearrange 3x+y =-5 to solve for y:

y = -3x-5

substitute -3x-5 for y into the second equation:

12x + 3y = 13

12x + 3(-3x-5) = 13

12x - 9x - 15 = 13

3x = 28

x = 28/3

y = -3x-5 = -33

solution: (28/3, -33)
