Charlotte bought 46 pens and pencils.

Each pen costs $6 and each pencil costs $4.
How many penicls she buy?

anser is 1

42 + 4

7(6) + 4(1)

To find out how many pencils Charlotte bought, we can use the information given.

Let's assume that the number of pencils Charlotte bought is "x".

We also know that Charlotte bought a total of 46 pens and pencils. Therefore, the equation we can form is:

x + (46 - x) = 46

Simplifying this equation, we have:

x + 46 - x = 46

By canceling out the x terms, we are left with:

46 = 46

This equation is always true, indicating that any value of x would satisfy the equation. Therefore, we can conclude that Charlotte bought any number of pencils.
