Tom has 7 more silver dollars than jimmy. Together they have a total of 71 silver dollars . How many silver dollars does tome have

Let Jimmy have x silver dollars

then tom have 7+x silver dollars .

from the given condition :

x + x+7 = 71

2x = 71-7

2x=64

x=32

then 32+7 = 39

then tom have 7+x silver dollars .

from the given condition :

x + x+7 = 71

2x = 71-7

2x=64

x=32

then 32+7 = 39

so tom will have 39 silver dollars.
