A textbook store sold a combined total of 370 math and chemistry textbooks in a week. The number of chemistry textbooks sold was 52 less than the number of math textbooks sold. How many textbooks of each type were sold?

NUMBER OF MATH TEXTBOOKS SOLD:

NUMBER OF CHEMISTRY BOOKS SOLD:

Answer 1

number of math textbooks sold: 211

number of chemistry textbooks sold: 159

Explanation:

let
`x` be the number of math textbooks sold

let
`y` be the number of chemistry textbooks sold

`y=x-52`

`y+52=x`

`x+y=370`

`y+52+y=370`

`2y=318`

`y=159`

`x=159+52`

`x=211`
