Answer:
x + 30 = 110, x = 80
Explanation:
The magazine has 23 full-page and 14 half-page ads,
→ There are 23 + 14/2 = 23 + 7 = 30 pages ads.
Let x represent the number of pages of articles in the magazine. Since the magazine has 110 pages in total,
→ The number of pages of ads + The number of pages of articles = Total pages
→ 30 + x = 110
→ x = 80
