James and Ken had a total of 1980 toy cars altogether. After James gave away 2/5 of his toy cars to his brother, the number of James's toy cars left to Ken's toy cars was in the ratio of 6:5. How many toy cars did Ken have?

assuming that Ken was the brother who got the toys from James, then
[3/5 (1980-k)] / [k + 2/5 (1980-k)] = 6/5
Ken had 180 and James had 1800
check:
Ken gave 2/5 * 1800 = 720 cars to Ken, so they ended up with
1080/900 = 6/5
[3/5 (1980-k)] / [k + 2/5 (1980-k)] = 6/5
Ken had 180 and James had 1800
