Answer:

One equation to set up is 5x+6 = 16

That equation solves to x = 2

You bought 2 binders

==================================================

Explanation:

x = number of binders

5x = cost of all the binders only ($5 each)

2*3 = 6 = cost of all 3 notebooks only ($2 each)

5x+6 = total cost of the 3 notebooks and x binders

5x+6 = 16 is one possible equation to set up

Other equations are possible.

------------

Let's solve for x.

5x+6 = 16

5x = 16-6 ... subtracted 6 from both sides

5x = 10

x = 10/5 .... divided both sides by 5

x = 2

You bought 2 binders

-------------

Check:

1 binder = $5

2 binders = 2*5 = $10

Add this onto the $6 spent on the notebooks to get 10+6 = 16 dollars total. The answer is confirmed.

Answer:

2 binders

Step-by-step explanation:

3(2)+x=16

6+x=16

x=10

binders are $5 each

2 binders
