I AM SO LOST HERE

Question

Kamden and Jace had some marbles. Kamden gave away 18 marbles and Jace gave away 1/3 as many marbles as Kamden. Jace had 2 more marbles left than the marbles he gave away. Kamden had twice as many marbles left as Jace. How many marbles did Kamden and Jace have in total at first?

Answer 1

k-18, j-18/3, k-18 = 2(j-6) = 2j-12, k-2j = 6

j-6 = 2+6 = 8, j=14 = Jace at first

k=2j+6 =2(14)+6 = 28+6 = 34 = kamden at first

(j,k) = (14,34)

kamden gave 18 away leaving 34-18 = 16 left. Jace gave 6 away leaving 14-6 = 8 left

Jace had 2 more than he gave away 8=2+6
