Answer:
(-2 , -2)
Step-by-step explanation:
Here,
(-6,-4)=(x1,y1)
(2,0)=(x2,y2)
Mid point formula,
(x,y)=(x1+x2/2 , y1+y2/2)
=(-6+2/2 , -4+0/2)
=(-2 , -2)
To solve, set an equation:
First Number: x
Second Number: 2x
x+2x=36
3x=36
divide both sides by 3
x=13
First Number: (x) 12
Second Number: (2x) 24
Answers: 12 and 24
