Answer:
Here is your answer
Let the first no. be x and let the second no. be y
According to question
X+y=13
X=13-y.... 1
Also
X-y=7
X=7+y..... 2
From 1 and 2
13-y = 7+y
13= 7+y+y
13= 7 + 2y
13- 7 = 2y
6=2y
Y=3
Putting value of y=3 in 1
X = 7+ y
X= 7+3
X = 10 and Y = 3 Ans.

Given,
Assume
Number be x and y respectively
So,
x + y = 13 ....... (1)
x - y = 7 ........... (2)
x + y + (x - y) = 13 + 7
x + y + x - y = 13 + 7
2x = 13 + 7
2x = 20
x = 10
Hence,
x + y = 13
10 + y = 13
y = 13 - 10
y = 3
Therefore,
