x = - 1

y = - 3

Step-by-step explanation:

We have two equations:

x + y = - 4 (1)

y = 2 * x - 1 (2)

What we will do is substitute (2) in (1) and we are left;

x + 2 * x - 1 = - 4

3 * x = - 4 + 1

3 * x = - 3

x = - 3/3

x = - 1

Now, to find out and, I replace in (2), like so:

y = 2 * ( - 1) - 1

y = - 2 - 1 =

y = - 3

Therefore, the values are:

x = - 1

y = - 3
