Solve 4 equations 15 points each so 60-65 points and brainliest

B  x=−1, y=−6

Step-by-step explanation:

Elimination method

Multiply the first equation by -3,and multiply the second equation by 1:

−3(3x+y=−9)

1(9x+4y=−33)

−9x−3y=27

9x+4y=−33

Add these equations:

y=−6

Plug it back into any given equation to solve for x:

3x+−6=−9

Solve for x:

x=−1
