Question

cost of pen is 2 and half times the cost of pencil express the situation as a linear equation in two variable x is equal to half y 2x=5y​

Answer 1

Answer:

2x=5y

XY=5/2

XY=2.5

Step-by-step explanation:

seeeeeeeeee upppppppppppppp

Answer 2

Step-by-step explanation:

Let the cost of the pen be x and that of pencil be y

Now,

According to the Question,

x = 2½(y)

Now changing the mixed fraction to improper

so,

x = (5/2)y

x = 5y/2

so,

2x = 5y

2x - 5y = 0

So, now it is expressed as linear equation

Hope it helped and you understood it........All the best
