Question

8 was subtracted from a number. Then, that difference was multiplied by 2, after which that result was divided by 11. If the result was negative 2 what was the initial number

Answer 1

-3

Explanation:

Let's call the initial number by 'x'.

First we have x - 8

Then, we have 2*(x-8)

Then, we have 2*(x-8)/11

And this result is equal to -2

So, we need to solve the equation 2*(x-8)/11 = -2

2*(x-8)/11 = -2

(x-8)/11 = -1

(x-8) = -11

x = -3

The inicial number is -3
