Question

Two step equations

Sally sold half of her comic books and then bought eight more. She now has twelve. How many did she begin with?

Answer 1

8

Explanation:

Since she now has 12, subtract 8 because of the 8 she before added.

Now, you're left with 4.

The 4 is half of what she originally had, leading up to the fact that the answer is 8.

Sally began with eight comic books.
