Answer 1

Answer:

x=5

Step-by-step explanation:

Given,

Pen's cost is rupees 10

Pencil's cost is rupees 7

So let the cost of pen be 10x

Cost of pencil be 7x

As per the question,

10x+7x=85

17x=85

x=85/17

Therefore

x=5

Answer 2

Answer:

cost of one pen=10

cost of one pencil=7

let the number of pens purchased be x andnumber of pencils purchased be y

then 10x+7y=85
