the sum when a number is used as an addend five times is equal to the difference of 40 and 30

Sagot :

Let the addend be N:
Five times the addend N ⇒  5N

Equation:

5N = 40 - 30
5N = 10
5N/5 = 10/5

N = 2

The addend is 2.

To check:

2 + 2 + 2 + 2 + 2 = 40 - 30
10 = 10

OR:

5 (2) = 40 -30
10 = 10
