a textbook store sold a combined total of 229 chemistry and math textbooks in a week. the number of chemistry textbooks sold was 53 more than the number of math textbooks sold. how many textbooks of each type were sold
Let the number of chem books be C, and number of math, M

Then we get: C + M = 229 ------- eq (i)

Also, C = M + 53 ------- eq (ii)

I hope you know what to do now, because I think I've done most of the work for you.

Hint: I would use SUBSTITUTION!
