Well, assuming you typed this in correctly...
2y+10+2x=0
2y+2x=-10
But this is all you can get, because there is not enough information {you at least did not include enough}.

Answer:
x=3±√41/8
Step-by-step explanation:
If you plug in x with the following points and see if the equation is equal to the answer. Since all the points are at the negative side. The first equation is out of the list.
x= the x point
y= the y point
Answer:
8x - 3y = 12 _______( 1 )
5x = 2y + 7 _______( 2 )
On further solving ( 2 ), we get
5x - 2y = 7 _______( 3 )
Multiply ( 1 ) by 2
16x - 6y = 24 _______( 4 )
Multiply ( 3 ) by 3
15x - 6y = 21 _________( 5 )
Subtract ( 4 ) and ( 5 )
( 16x - 6y ) - ( 15x - 6y ) = 24 - 21
16x - 6y - 15x + 6y = 3
Put this in ( 2 )
5 ( 3 ) = 2y + 7
15 = 2y + 7
2y = 15 - 7
2y = 8
y = 8 / 2

Answer:
Domain = -3, 2, -8
Range = 1, 6, -6
Function? No
Step-by-step explanation:
Domain = x-values(no repeats)
Domain = -3, 2, -8
Range = y-values(no repeats)
Range = 1, 6, -6
Function?
No, the domain is repeating. Range can repeat but domain cannot
