Question

ram and hari have some pencils. ram said to hari, if you will give me 10 pencils, I will have the twice the pencils left with you. represent this situation as a linear equation in teo variables.​

Answer 1

Answer:

2y-x=30

Step-by-step explanation:

let the number of pencils with

ram be=x

hari be=y

if hari gave 10 pencils, that is y-10

if ram gets that 10 pencils he has x+10

so

(x+10)=2(y-10)

x+10=2y-20

2y-x=30

Answer 2

Answer:

x+10 = 2( y-10 )

Step-by-step explanation:

x is what ram had originally and y is what hari had originally. if hari gives 10 pencils to ram then ram will have +10 anf hari will have -10

So what hari has ( which is y-10 ), twice (which is times 2) will be what ram has ( which is x+10 )
