What is x equals 12x plus 8?

Answer 1

You need to find a value of x where the following is true:

x = 12x + 8

First, subtract x from both sides so the only terms with x are on the right:

x - x = 12x + 8 - x

0 = 11x + 8

Now, subtract 8 from both sides so the only terms without x are on the left:

-8 = 11x

Finally, divide both sides by 11 so x is by itself on the right:

-8/11 = x

The answer is -8/11, which is about -0.7273.
