Answer:
(-1,3)
Step-by-step explanation:
–2x – 9y=-25
-4x – 9y=-23
Multiply the second equation by -1
4x + 9y=23
Add this to the first equation
–2x – 9y=-25
4x + 9y= 23
-----------------------
2x = -2
Divide each side by 2
2x/2 = -2/2
x = -1
Now we need to find y
4x+9y = 23
4(-1) +9y = 23
-4 +9y = 23
Add 4 to each sdie
-4+4 +9y = 23+4
9y = 27
Divide each side by 9
9y/9 = 27/9
y =3

Step-by-step explanation:
An ??????
Well to figure this out, we will use mathematics. You do 90% of the an and then do 39 which is close to 90 and then because it has 9 in the number that is given. So, 213 is incorrect. 90% of the things like 213, = 39. And if it equals 39, then here comes 90. 90 comes in as a number to help, but 213 does to. So we will divide the number 9. 9 = 2, and since 213 has the first digit 2 in the number, that means that the answer is An number that equals 2 is the common side of two consecutive angles in a polygon.
Just a answer!
