Answer:
20 and 10
Step-by-step explanation:
let the 2 numbers be x and y.
Case1: x>y
x=2y -------(1)
30 - x=22 - y - 2
x - y =10 --------(2)
put (1) in (2)
2y - y = 10
y = 10
x= 2y= 2*10=20
Case2: y>x
y=2x -------(1)
30 - y=22 - x - 2
y - x =10 --------(2)
put (1) in (2)
2x - x = 10
x = 10
y= 2x= 2*10=20
therefore the 2 no. are 20 and 10
hope this is helpful:)
