Answer:

X = -1   Y = 4

Step-by-step explanation:

Put the 7y over so it is 27-7y

after that you fill in the x on the top formula with (27-7y)

From there you solve like normal for Y, which ends out being 4.

Once you have that you can plug 4 into the Y spot in the bottom formula and just solve for X
