Question

The sum of two integers is 5 their difference is 3 what are the two integers

Answer 1

x+y=5
x-y=3

x=3+y
(3+y)+y=5
2y+3=5
2y=2

y=1
x=4

The answer is 1 and 4

Answer 2

The two integers are 4 and 1.

Assuming the two integers are x and y, the first expression would be:

x + y = 5

The second expression would be:

x - y = 3

You can solve this simultaneously:

x + y = 5

x - y = 3

Using substitution, express x in terms of y:

x - y = 3

x = 3 + y

Solve:

x + y = 5

3 + y + y = 5

3 + 2y = 5

2y = 5 - 3

y = 2 / 2

y = 1

x = 3 + 1

x = 4

In conclusion, the two numbers are 4 and 1.
