The calculated values of x and y are x = 3 and y = -5
How to determine the values of x and y
From the question, we have the following parameters that can be used in our computation:
4x + y = 7
x + y = -2
Subtracting both equations, we have the following equation
3x = 9
So, we have
x = 3
Recall that
x + y = -2
So, we have
y = -2 - x
This gives
y = -2 - 3
Evaluate
y = -5
Hence, the values of x and y are x = 3 and y = -5
