Question

arvind and vinod have some eraser. arvind said to vinod if you give me 10 eraser i will have twice the eraser left with you . make a linear equation for this situation

Answer 1

Let the number of eraser arvind had be x and that of vinod be y

Then the required liner equation will be ;

(x+10) = 2(y-10)
x+10 = 2y-20
x-2y+30 = 0
-------------------------------

Answer 2

Answer:

= 2y -x - 30 = 0

Step-by-step explanation:

Let Arvind erasers be  x and vinod's y

∴ x+10 = 2*(y-10)

= x+10 = 2y-20

= 2y-x = 30  

= 2y-x - 30 = 0
