Hello,
Let's have x be the unknown number. Here's how the equation will look.
2x-7x=40
Now we need to solve what x is. Adding 2x - 7x is -5x so
-5x = 40
Divide both sides by -5
x = -8
There you go, you can plug -8 into the original equation and it works.
-8 is the answer
you're welcome

5N = 40

N =

Therefore, the number, or N =
