Answer:
What does n equal?
Step-by-step explanation:
A question we can represents the following equation is:
"What does n equal?"
Since, n is a variable we don't know what it is before solving it.
Thus, a question we can ask is " what does n equal?"
Solve equation if needed:
22 - n = 15
Subtract 22 from both sides
-n+22-22=15-22
-n = -7
Divide both sides by the same factor
-n/-1 = -7/-1
n = 7

Answer:
See below.
Step-by-step explanation:
John had 22 books. He gave away a number of books, but he forgot the number of books he gave away. Now he has 15 books. Let n be the number of books he gave away. Write and solve an equation an equation to find the number of books John gave away.
22 - n = 15
Subtract 22 from both sides.
-n = -7
Multiply both sides by -1.
n = 7
Answer: John gave away 7 books.
