    Answer: Kristin bought 6 Math books and 5 English books.

    Step-by-step explanation: Let x be the number of math books and y the number of english books.

    Relation: 306=26x+30y

    11=x+y

    Solve using elimination method so you would get that y=5 then replace y=5 in the first equation to find x which is 6
