Students A and B originally planned to do the same number of practice questions every week. In fact, A did 18 more questions a week, while B was lazy and did 14 fewer questions a week. As a result, the amount of questions B did in three weeks was only Equivalent to a week to do the amount of questions. May I ask: How many questions did they plan to do each week?
甲、乙两位学生原计划每周做同样数量的练习题，实际上甲每周多做了18道题，而乙偷懒每周少做了14道题，结果乙三周的做题量只相当于甲一周的做题量．请问：他们原计划每周做几道题？
