X + y = 12
x - y = 4
From the second equation we can see that x = 4 + y
We can plug this into the first one and get:
4 + y + y = 12
4 + 2y = 12
2y = 12-4
2y = 8
y = 4
And then we can plug that into “x” and get that x = 4 + 4, or x=8
#5= 37.5:62.5 i think its good
Step-by-step explanation:
A , B , C is quadrilateral
D and E is not quadrilateral
Do -104 negitiive 8 times.then you will have it.
The coordinate of the hive is the point of interaction of the two lines.
We have the two equations:
