Question

Algebra 1 step by step worksheet

 

Answer 1

Let P be the number of pens sold and B be the number of books. 

 

P + B = 11

 

5P + 12B = 83

 

Multiply equation 1 by - 5

 

-5P - 5B = -55

 

Now add both these equations together

 

7B = 28

 

B = 4

 

P = 7

 

The number of fancy pens sold were 7 and books sold were 4. Good luck with the rest of your problems.
