To solve the system of equations, we can substitute the value of y from the second equation into the first equation:

2x + 3x + 2 = -4
5x + 2 = -4
5x = -6
x = -6/5

Now, we can substitute this value of x back into the second equation to find the value of y:

y = 3(-6/5) + 2
y = -18/5 + 2
y = -18/5 + 10/5
y = -8/5

Therefore, the solution to the system of equations is x = -6/5 and y = -8/5.

So, the answer is option a: negative 6 over 5, negative 8 over 5.
A. b. c. or d.
Apologies for the oversight. The correct answer choice is:

b. negative 8 over 5 comma negative 6 over 5
