according to question
x + y = 70
x -y = 10
x= 70- y
70 -2y = 10
30 = y
40 = x
x + y = 70
x -y = 10
x= 70- y
70 -2y = 10
30 = y
40 = x

Answer: 40 and 30
Step-by-step explanation:
Let the two numbers be x and y
x + y = 70
x - y = 10
By adding these two equations, we get
2x = 80
x = 80/2
x = 40
x - y = 10
40 - y = 10
y = 30
The two numbers are 40 and 30.
