Question

find two numbers whose sum is 70 and difference is 10.​

Answer 1

according to question

x + y = 70

x -y = 10

x= 70- y

70 -2y = 10

30 = y

40 = x

Answer 2

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.
