Question

The sum of numbers is 28. the difference of two numbers is -2. find the numbers​

Answer 1

I believe 15 and 13. 13-15=-2 and added is 28....?

Answer 2

x=13 and y=15

Explanation:

Let the 2 numbers be x and y

ATQ,

x+y = 28 ------ eqn.1

x-y=-2 -------- eqn.2

Adding both the equations:

x+y=28

+x-y=-2

_______

2x = 26

Therefore x=13

Now substituting the value of x in eqn. 1

x+y=28

13+y=28

Therefore y=28-13

=15
