It takes 12 days for teams A and B to complete a project together. If the two teams complete (3/5) of the project, it will take another 6 days for Team A to do the rest of the project alone. How many days will it take Team B to complete the project alone?
甲乙两队合作完成一项工程需12天，如果两队完成(3/5)工程后，剩下的工程由甲队独做又用了6天．乙队单独完成这项工程要多少天？
