Question

if the addition of two number is 25, difference 15 means what are these two numbers

Answer 1

-21 and 46 ,beacuse here 25 is made up of two numbers then we will let the first no. be x and the second no. be 25-x ,because 25 is made up by the sum these no.

Answer 2

Hey mate here is your answer.....
Let the two no.s be x&y.
x+y=25_______(1)
x-y=15______(2)
From 1
x=25-y
Pitting the value of x in equation 2
x-y=15
25-y-y=15
-2y=15-25
-2y=-10
y=5
Putting the value of y in equation 1
x=25-5
x=20
