Answer:

1. Y

2. N

3. N

4. N

Step-by-step explanation:

Let's use the second equation, since it seems to be easier to use.

To check if an ordered pair is a solution, plug it in to the equation.

1. -10+18=8 --> Y

2. 25-12=13 --> N

3. 0-9=-9 --> N

4. 35-27=8 --> N

Edit : The 4th equation doesn't work for the first equation, whereas the first one still does.

Answer:

(-2,-6)

Step-by-step explanation:

-9x +2y = 6

5x - 3y = 8

1) Make one of the coefficients the same - y.

-9x +2y = 6 * 3

5x - 3y = 8 * 3

-27x +6y = 18

10x - 6y = 16

2) Add the new equations.

(-27x +6y = 18) + (10x - 6y = 16)

(-27x +6y) + (10x - 6y) = 18 + 16

-17x = 34

3) Divide to find the value of x

-17x = 34

x = 34/-17

x = -2

4) Substitute x into either equation to find the value of y.

-9(-2) +2y = 6

18 +2y = 6

2y = -12

y = -12/2

y = -6

5(-2) - 3y = 8

-10 - 3y = 8

-3y = 18

y = 18/-3

y = -6

Your answer is (-2,-6).
