Determine if the point (-1,-1) is a solution to the system of equations.
2x+1=5
X-Y=-2
• Yes, it is a solution.
• No, it is not a solution.
To determine if the point (-1,-1) is a solution to the system of equations, we need to substitute the values of x and y into each equation and see if the equations are satisfied.
For the first equation, 2x + 1 = 5, we substitute x = -1 and evaluate:
2(-1) + 1 = -2 + 1 = -1
So, this equation is not satisfied.
For the second equation, x - y = -2, we substitute x = -1 and y = -1 and evaluate:
-1 - (-1) = -2
Simplifying, -1 + 1 = 0 = -2
So, this equation is also not satisfied.
Therefore, the point (-1,-1) is not a solution to the system of equations. The answer is:
• No, it is not a solution.
