Question

I need help on this question(PLEASEEEE)

Answer 1

Place an X for the first box as [Yes], [No], [No]

Step-by-step explanation:

When we enter x=2 and y=1 into the first system of equations, we can see that both conditions are met. Thus the answer to this system is (2, 1).

When x=2 and y=1 are substituted into the second system of equations, we obtain 1=-3 and 1=-2, which are false, and so (2, 1) is not a solution for this system.

When x=2 and y=1 are substituted into the third system of equations, the results are -3=-2 and 1=-3, which are false, hence (2, 1) is not a solution for this system.

Answer 2

Yes, No, No.

Step-by-step explanation:

• For the first system of equations, we substitute x=2 and y=1 into each equation and we see that both are satisfied. So (2, 1) is a solution for this system.

• For the second system of equations, substituting x=2 and y=1 into each equation, we get 1=-3 and 1=-2, which are not true, so (2, 1) is not a solution for this system.

• For the third system of equations, substituting x=2 and y=1 into each equation, we get -3=-2 and 1=-3, which are not true, so (2, 1) is not a solution for this system.
