Question

10 less than a number is the same number doubled. What is the number?

Answer 1

-10

Step-by-step explanation:

We must write an equation

X is the number that we need to find

X - 10 = 2X

To solve this equation, we must substract x from each side

x-10-x = 2x - x

This results in

-10 = X

So the answer is -10
