b) { y = -x + 1
y = -2x - 2

Solving the equations we get: x = -3, y = 4

The solution set is: (-3,4)

Step-by-step explanation:

We need to solve the system of equation and find value of x and y

The system of equation given is:

Let:

We would use substitution method.

Put value of y from eq(1) into eq(2) and find value of x

So, we get x = -3

Now, for finding value of y, put value of x = -3 into equation 1

So, we get y=4

Solving the equations we get: x = -3, y = 4

The solution set is: (-3,4)
