Question

Cost of pen is two and half times the cost of a pensil. Express this situation as a linear equation in two variables.​

Answer 1

Answer:

Let the cost of pencil be x

Let the cost of pen be y

Therefore, 2 and a half times pencil = 2 1/2 x

2 1/2 x = y

Pls mark as the brainliest answer

Answer 2

Answer:

2x-3y=0

Step-by-step explanation:

let the cost of the pen be x and cost of pencil be y. Then,

x= 2 and ½ times of y

x= 3/2 y

2x=3y

2x-3y= 0
