Answer:

(1, -4)

Step-by-step explanation:

In this system, multiply the top equation by -4. this will give you

-4x - 12y = 44

4x + 7y = -24

the x values can now cancel out, and add the other values together

-5y = 20

y = -4

now, substitute y = -4 in for one of the starting equations

x + 3(-4) = -11

x - 12 = -11

x = 1
