Help me!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer:

9. x=-6, y=0

10. x=-9, y=-10

11. x=3, y=-1

Step-by-step explanation:

2x-9y=-12\\3x+18y=-18

Multiply the first equation by 2.

4x-18y=-24\\3x+18y=-18

Add the equations.

7x=-42

x=-6

We figured out x now we have to figure out y. To figure out y plug in x into any equation.

2(-6)-9y=-12

-12-9y=-12

-9y=0

y=0

Your answer is x = -6 and y = 0 for number nine.

6x+3y=24\\2x+3y=-12

Change the signs of the second equation becuase 3y and 3y are both positive. We need one of them to be negative.

6x+3y=24\\-2x-3y=12

Add them.

4x = 36

x=9

Now we have to figure out y.

2(9)+3y=-12

18+3y=-12

3y=-30

y=-10

x=-9 and y=-10 is your answer to number ten.

10x+5y=25\\-7x-3y=-18

30x+15y=75\\-35x-15y=-90

-5x=-15

x=3

-7(3)-3y=-18

-21-3y=-18

-3y=3

y=-1

x=3 and y=-1 is the answer to number eleven. I hope this helps! Let me know if I got anything wrong.

Step-by-step explanation:

4 x 3 = 12, 12 divided by 2 ( x 1/2 ) = 6

6 x 2 = 12

3 x 11 = 33

4 x 11 = 44

5 x 11 = 55

12 + 33 + 44 + 55 = 144
