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

Answer:

number of math textbooks sold: 211

number of chemistry textbooks sold: 159

Step-by-step explanation:

let $x$ be the number of math textbooks sold

let $y$ be the number of chemistry textbooks sold

$y=x-52$

$y+52=x$

$x+y=370$

$y+52+y=370$

$2y=318$

$y=159$

$x=159+52$

$x=211$
