Question

The difference between a number y and another number is 20.Represent the other number in terms of y.
​

Answer 1

Answer:(20+y)

Step-by-step explanation:

Let the another number be x.

Then by question,

(y-x)=20

Or, x=(20+y)

Hence the required another number (x) in terms of y is

x=(20+y)

Answer 2

Answer:

y ± 20

Step-by-step explanation:

let the other number be N

N-y = 20 , N = y + 20

or

y - N = 20 , N = y - 20
