38 = 2X + 4
or is it
38 = 2(x+4)?
.
Let's solve it for the second, and then you can repost if it's supposed to be the first.
.
38 = 2(x+4)
Distribute
38 = 2x + 8
Subtract 8 from each side
30 = 2x
Divide each side by 2
15 = x

Let your unknown number be "x"
The sum of your number and four is x+4, and twice the sum of that number and four will be 2(x+4)
And you have thirty-eight equals that, so that means you have
2(x+4) = 38
let's solve
2(x+4) = 38
x+4 = 19
x = 15
So the value of your number is 15
