form of linear equation in two variables. Also represent it
graphically.​

Answer 1

Step-by-step explanation:

Cost of one pen =Rs.x

Therefore cost of 3 pens=Rs.3x

Cost of one pencil=Rs.y

Therefore cost of 2 pencils =Rs.2y

Then according to question 3x+2y=Rs.34

Answer 2

Answer:

Cost of one pen =Rs.x

Therefore cost of 3 pens=Rs.3x

Cost of one pencil=Rs.y

Therefore cost of 2 pencils =Rs.2y

Then according to question 3x+2y=Rs.34
