Do you know what do we have to do next?

x+y=620
y=x+20
We can take the second equation and plug it on the first one.
Like this:
x+(x+20)=620
How can we continue now?

distribute your x then solve by adding like terms first

Answer 8

then 20 - from both sides that leaves 2x=600
now divide

Answer 14

But x is the number of man, right?

y=300+20
y=320
