Question

The difference between twice a number and a number that is 5 more than it is 3. Which of the following equations could be used to find the value of the number, n?

Answer 1

Explanation:

Let the number = x

2x - (x + 5) = 3 Answer

Now Let's solve it.

2x - x - 5 = 3

x - 5 = 3

x = 8

Check

2*8 - (8 + 5)

16 - 13

3

which is exactly what the right hand sign is.
