Question

Two fewer than a doubled number is the same as the number decreased by 38. Find the number. If n is "the number," which equation could be used to solve for the number?

Answer 1

Answer: n=-36

Explanation:

Let the number be n

2 fewer than a doubled number can be written as 2n-2

The number decrease by 38,can be written as n-38

Equate both

2n-2=n-38

Collect like terms

2n-n=-38+2

n=-36

The number is -36
