Do you have to solve it?
Her equation doesn't fit the word problem! It says several 2 pounds books but she put it as if there was one. She should have wrote the equation like this:
3 + 2x = 20 (where x represents the unknown amount of boxes)
and than you can just solve for x to find how many books there are
3 + 2x = 20
2x = 20
x = 10
So there are 10 books!
I hope that helps! Let me know if you have any questions :3

Given : 
To find : The solution to the equation given
Solution :
Step 1- Write the given expression
Step 2 - Using logarithmic laws
Step 3 - To remove log-base 2, we need to raise the left and right hand terms to power 2.
Step 4 - Solve the quadratic equation
Either x=8 or x=-2
We neglect x=-2 because negative value is not defined in log.
Value of x=8
