Re write the given in math language rather than English:
Let n be this number:

(n - 2).(2) = n-38

2n - 4 = n - 38

n = -34

Answer:

The required equation is : 2·(n - 2) = n - 38

Step-by-step explanation:

Let the number be n

Two fewer than the number : n - 2

Two fewer the number is doubled : 2·(n - 2)

Number is decreased by 38 : n - 38

Given : Two fewer than a number doubled is the same as the number decreased by 38

⇒ 2·(n - 2) = n - 38

⇒ 2n - 4 = n - 38

⇒ n = -34

Hence, The required equation is : 2·(n - 2) = n - 38
