Answer:

Step-by-step explanation:

You start with creating let statements.

Let x = the cost of each pencil.

Let y = the cost of each eraser.

Let z= the cost of each pen.

Then, you’d fill in information from the problem.

3x + 4y = 65

2z + y = 35

Now, you’d solve like a system of equations; meaning you can do elimination or substitution.
