Determine if the point (-1,-1) is a solution to the system of equations.
2x+y=5
X-y=-2
Yes, it's a solution
No, it's not a solution
To determine if (-1, -1) is a solution to the system of equations, we need to substitute the values of x and y into the equations and see if both equations are satisfied.
Equation 1: 2x + y = 5
Substitute x = -1 and y = -1:
2(-1) + (-1) = 5
-2 - 1 = 5
-3 = 5
This equation is not satisfied.
Equation 2: x - y = -2
Substitute x = -1 and y = -1:
-1 - (-1) = -2
-1 + 1 = -2
0 = -2
This equation is also not satisfied.
Therefore, (-1, -1) is not a solution to the system of equations.
