Answer
$46,78$
Work Step by Step
let's call the two numbers $x, y$
We know that:
$x + y = 124$
and
$x - y = 32$
By the first equation
$x + y = 124$
$x + y - y = 124- y$
$x = 124- y$
let's use the second equation and switch $x$ for $124-y$
$x - y = 32$
$124-y - y = 32$
$-2y + 124= 32$
$-2y + 124- 124= 32- 124$
$-2y = -92$
$-2y \times \frac{-1}{2} = -92\times \frac{-1}{2}$
$y = 46$
Therefore
$x = 124- y = 124- 46= 78$
