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
