Question 568898
Let 
Present age of Skyler = s
Present age of Jason = j

Given
Skyler is 20 years older than Jason
s=j+20.................(1)
In 8 years
Skyler will be = s+8
Jason will be = j+8
Then
Skyler will be twice as old as Jason
s+8=2(j+8)
s+8=2j+16
s=2j+16-8
s=2j+8..............(2)
Put the value of s from (1) to (2)

j+20=2j+8
j-2j=8-20
-j=-12
Multiply by -1 both sides
(-1)(-j)=(-1)(-12)
j=12

Put the value of j in (1)
s=j+20
s=12+20
s=32


Present age of Skyler = s = 32 years old
Present age of Jason = j = 12 years old
