Question

Show the condition using variable x and y: Two numbers differ by 3
​

Answer 1

Given: Two numbers differ by 3

To Find : Show the condition using variable x and y

Solution:

Two numbers differ by 3

case 1 if x > y

=> X - y = 3

Case 2 if y > x

=> y - x = 3

=> -(x - y) = 3

=> x - y = - 3

from both

X - y = +3

=> | x - y| = 3 =

Hence

X - y = ±3 or 1 x - y = 3
