Answer: he bought 12 books.
Step-by-step explanation:
Let x represent the number of books that Greg bought.
Greg ordered some books online for $6 each. This means that x books would cost $6x
He paid a total of $3 for shipping. The total cost of the purchase was $75.00. This means that
6x + 3 = 75
Subtracting 3 from the left hand side and the right hand side of the equation, it becomes
6x + 3 - 3 = 75 - 3
6x = 72
Dividing the left hand side and the right hand side of the equation by 6, it becomes
6x/6 = 72/6
x = 12

Step-by-step explanation:
There can be a lot of math expressions that may equal 13. Here are some of the expressions that equal 13.
Now, let us consider some interesting expression

If the value of x = 2, then the expression will be equal to 13.
i.e.
∵ when x = 2
Considering a word problem
<em>'Tom has 10 oranges while Tony has 3 more oranges than Tom. How many oranges Tony has?</em>
Let 'x' be the number of oranges Tom has.
The number of oranges Tony has = x + 3
as Tom has 10 oranges, so x = 10
Therefore, the number of oranges Tony has = x + 3
= 10 + 3 = 13
Therefore, the number of oranges Tony has = 13
