Question

The difference between 55 and twice an
unknown number, x, is 95. Find x.

Answer 1

I'm not sure if twice an unknown number means that number squared or

2x.

Answer 2

x = - 20

Explanation:

twice the unknown number is 2x , then difference is 55 - 2x and

55 - 2x = 95 ( subtract 55 from both sides )

- 2x = 40 ( divide both sides by - 2 )

x = - 20
