Answered by Steve
Add 14 to their ages, and if Joan is x years old now, you have

x+20 + 14 = 2(x+14)

| Now |+ 14 years
------|------|------------------------
Kevin | x+20 |x+20+14;2(x+14
------|------|------------------------
Joan | x |x+14
------|------|------------------------

x+20+14= 2(x+14)
x+34= 2x+28
34-28=2x-x
x=6
x+20= 6+20= 26

So, Kevin is 26 while Joan is 6.

But, check my work.
So Substitute.
6+20+14 = 2(6+14)
40=12+28
40=40
I am right yay!!!!!
