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
