1. Answer:

   4x+5y=25

   Step-by-step explanation:

   let the cost of each pen be indicated by x

   so, for 4 pens its indicated by 4x

   let the cost of each pencil be indicated by y

   so, for 5 pens its indicated by 5y

   So, the total sum is given by 4x+5y

   but given that total amount is 25

   ∴ The equation turns 4x+5y=25

   Hope it helps
