When 8 is added to the number that is produced by doubling the number x, the result is equal to 8 times the number that is 5 les

Natasha_Volkova [10]

Hello. In order to solve this problem, you need to write an equation. Hence, you determine this equation:

8 + 2x = 8(x-5)
8 + 2x = 8x - 40
8 + 40 = 8x - 2x
48 = 6x
x = 8.
