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

Hope it helps :)

Let the number of erasers with Arvind be x and the number of erasers with Vinod be y

If we add 10 woth x it would be 2 (y-10)
i.e, x+10 = 2 (y-10)
x+10=2y-20
x-2y+30=0
So the equation for this problem is
x-2y+30=0
