Question

a number is twice another number. when the larger is subtracted from 50, the result is 2 more than the smaller is subtracted from 40. find the number

Answer 1

let a number is x and another y
x=2y
here,x is larger
50-x=2+40-y
50-40-2=x-y
8=x-2x
x=-8

Answer 2

Let larger number be x and smaller number be y
x=2y
50-x=40-y+2
Put x=2y
50-2y=42-y
50=42+y
y=50-42=8
x=2y=2*8=16
Therefore, larger number is 16 and smaller number is 8.
