Question

The value of two numbers has a sum of 20. Those same two numbers have a difference of -6. Find the value of those two numbers.

Answer 1

Answer: $-6,13$

Step-by-step explanation:

Given

The sum of the two numbers is 20

and the difference of the two is -6

Suppose, the numbers are x and y

$\therefore x+y=20\quad \ldots(i)\\\Rightarrow x-y=-6\quad \ldots(ii)\\\text{Solving} (i)\ \text{and}\ (ii)\ \text{we get}$

$\Rightarrow 2x=14\\\Rightarrow x=7$

$\therefore y=13$

Therefore, the numbers are $-6,\ \text{and}\ 13$
