The product of a number and 7, decreased by the number is equal to 42. Find the number.

1 answer:

8 0

$7$
this is the answer, its pretty simple. I'm not sure the mathematical procedures but if you plug in 7 you get 49. Then all you got to do is subtract by 7, because the question states the number is the same. So basically,
$7(7) - 7 = 42$
