Question

(plz answer I will mark you as brainlists)A pen cost twice as much as a pencil. if the cost of 5 pens and 6 pencil is rs96 find the cost of 6 pens and 5 pencil​

Answer 1

Answer:

let the cost of pencil be x

let cost of pen be y

ATQ y=2x

ATQ 6x+5y=96

put y=2x

6x+5(2x)=96

6x+10x=96

16x=96

x=96/16

x=6

y=2x

y=2×6

y=12

cost of 1 pen =12

cost of 1 pencil =6

Answer 2

Answer:

pecil = x

pen = y

a/q,

6x + 5y = 96

so,

x = 96 - 5y by 6 ( 96 - 5y / 6 )
