Answer: History textbooks sold = 236, Sociology textbooks sold = 118

Step-by-step explanation:

<u>Given</u>

- There are in total 354 books

- Let x be the number of sociology textbooks sold

- Let 2x be the number of history textbooks sold

<u>Solve</u>

Given

x + 2x = 354

Combine like terms

3x = 354

Divide 3 on both sides

3x / 3 = 354 / 3

x = 118

2x = 118 × 2 = 236

Hope this helps!! :)
