1. Answer:

   Erin has 7 pens and James as 28 pens.

   Step-by-step explanation:

   Let e = the number of Erin’s pens

   Let j = the number of James’ pens

   e + j = 35                          j = 4e

   substitute in 4e for j in the first equation above.

   e + j = 35

   e + 4e = 35

   5e = 35  Divide both sides by 5

   e = 7  Plug 7 in for e in either equation above.

   j = 4e

   j = 4(7)

   j = 28
