Solution

The system of equations is:

4x + 7y = -238 x + 5y = -1

To solve this system of equations, we can use the method of substitution or elimination. Here, I'll use the method of substitution.

First, let's isolate x in the second equation:

x = -5y - 1

Now, substitute x in the first equation:

4(-5y -
