X = -5 Y=-1

WORK BELOW

From the equation 8x + 7y = -47, substitute x with 4y - 1:

8(4y - 1) + 7y = -47

Simplifying the equation:

32y - 8 + 7y = -47
39y - 8 = -47
39y = -39
y = -1

Now, substitute the value of y into the equation 4y - 1 = x:

4(-1) - 1 = x
-4 - 1 = x
-5 = x

So, the values of x and y are x = -5 and y = -1.
