1 purse and 1 watch is 27€
2 purse and 1 watch is 41€
So we can see the watch is constant means 1 watch is every time but purse is increase by 1 in the next expression
So 41-27 = 14€ is one purse
because the watch is every time one, so the next value increase is by purse
1purse and 1watch = 27
We know,
1 purse is 14€
So 27-14=13€ is one watch
We can check by
1 purse is 14 so two purse is 14*2=28
28+13=41
Which is same as they said in second expression
Hope it help you!¡
