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.
