Question

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

Answer 1

tom has 39 silver dollars and jimmy has 32 silver dollars so together it makes 71 silver dollars

Answer 2

t=7+j  so we can say that

j=t-7

We are then told that

j+t=71, and using j from above this becomes

(t-7)+t=71

t-7+t=71

2t-7=71

2t=78

t=39

So Tom has 39 silver dollars.
