Question

Sixty less than some number is equal to the sum of twice the number and twelve. How do you find the number?

Answer 1

`x = -72`

Explanation:

We will make "some number" equal to `x`. And so we know:

`x - 60 = 2x + 12`

By keeping the equation balanced we can solve to:

`x - x - 60 - 12 = 2x -x + 12 - 12`

`-72 = x` or `x = -72`
