#2. Determine if the point −1,1 is a solution to the system of equations. x+2y=5 x−y=−2
yes its a solution
no it is not a solution
To determine if the point (-1, 1) is a solution to the system of equations, we substitute x = -1 and y = 1 into the equations and see if they both hold true.
For the first equation x + 2y = 5:
(-1) + 2(1) = 5
-1 + 2 = 5
1 = 5
The first equation is not true when x = -1 and y = 1, so (-1, 1) is not a solution to the system of equations. Therefore, the answer is no, it is not a solution.
