Question

tom has twice as many marbles as luke. together they have 39 marbles. how many marbles does tom have?

Answer 1

Tom has 26 marbles. Let x= the amount of marbles Luke has. If Tom has twice as much, the amount of marbles he has is represented as 2x. 2x+x=39. 3x=39. X=13, and since Tom has twice that amount, 13 times 2 is 26! Hope this helped! ;)

Answer 2

Tom has 26 marbles. if you need to show your work it would be 13x2= 26 and 26+13=39
