Tom and Jerry together have 50 marbles Tom has 17 marbles more than Jerry How many more marbles does Tom have?

Let the number of marbles Jerry has be ( x ). Then Tom has ( x + 17 ) marbles. Together, they have 50 marbles, so we can set up the equation ( x + (x + 17) = 50 ). Solving this gives ( 2x + 17 = 50 ), leading to ( 2x = 33 ) and ( x = 16.5 ). Thus, Tom has ( 16.5 + 17 = 33.5 ) marbles, which means Tom has 17 more marbles than Jerry.
