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
