Answer: Inconsistent.

Explanation:

The equation of the line in Slope-Intercept form is:


y=mx+b

Where "m" is the slope and "b" is the y-intercept.

Solve for "y" in each equation:

Equation 1


x=-5-y\\\\y=-x-5

Equation 2


4+y=-x+3\\\\y=-x+3-4\\\\y=-x-1

You can notice that the slope of the Equation 1 is:


m_1=-1

And the slope of the Equation 2 is:


m_2=-1

Observe that
m_1=m_2, then you can conclude that the lines are parallel and the System of equations has No solution.

When there is no solution the classification of the system of equations is: "Inconsistent".
