The total number of books is:
Answer:
s = 36
Step-by-step explanation:
So what you do is isolate the s.
1. Subtract 14 from both sides of equation. You should have:
1/3s = 12
2. To isolate the s, you multiply by 3 on both sides to get rid of the fraction on the left side. You should have:
s = 36
To verify, plug into original equation:
1/3*(36) + 14 = 26
1/3 * 36 = 36/3 = 12
12 +14 = 26
We can verify.

Divide! If you add three and four, you get seven. Subtracting four from seven, you get three. If you multiply three and four, you get twelve. If you then divide by four, you get back to 3. I hope this helped!
