Question

if the number is twice the another number and the sum of number 24 find the number ​

Answer 1

Answer:

let one number be x and other be 2x

x+2x=24

3x=24

x=8

2x=16

Answer 2

Answer:

The number is 16

let the first number be x,

and the other number be m. THEN,

x = 2m

x + m = 24      ( substitute 2m in place of x)

2m + m = 24

3m = 24

m = 24/3

m = 8

x = 2×8 = 16
