Question

one no.is twice the other and their sum is 8 .so the n. are...​

Answer 1

let one number be x

then the other number becomes 2X

According to question,

X + 2X = 8

3X = 8

X = 8/3

s

Therefore, one number is 8/3 and the other is (2*8/3) 16/3

Answer 2

Hey...

$let \: no. \: be \: x \: and \: y \\ \bold{ \pink{according \: to \: your \: ques}} \\ x = 2y \\ and \\ x + y = 8.....(i) \\ putting \: the \: value \: of \: x = 2y \: in \: eq(i) \\ 2y + y = 8 \\ 3y = 8 \\ y = \frac{8}{3} \\ and \: x = 2y \\ = 2( \frac{8}{3}) \\ = \frac{16}{3}$
