Step-by-step explanation:
Rotation of any point in the form of (x, y) about the origin O through 180 degree in anticlockwise or counterclockwise direction, it will takes the new position (-x, -y)
i.e,
The rule of rotation about the origin through 180 degree is given by:
For example:
Let the point A(-4, 6) rotate by the rule
then;
⇒the coordinate of image of the point A is, (4, -6)
Therefore, the rule represents is,
7x +(3x-5)+(8x+5)=180
simplify
18x=180
divide by 18
x=10
Answer:
Integer 1 is x
Integer 2 is y
x + y = -31
x - y = -55
Add:
2x = -86
x = -43
Substitute:
-43 + y = -31
y = 12
Therefore, the two integers are: 12 and -43
