Question

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

Answer 1

Luke has 13 marbles

Explanation:

t = number of marbles Tom has

l = number of marbles Luke has

t = 2l

t+l = 39

Substitute t = 2l into the second equation

2l + l = 39

Combine like terms

3l = 39

Divide by 3

3l /3 = 39/3

l = 13

Luke has 13 marbles

Tom has 2 * 13 = 26 marbles
