algebra

 4(x-28)=100   divide both sides by 4

x - 28  = 25      add 28 to both sides

x = 53

x=53

I do belive that you r answer is, yes, in fact:

x = 53

And I know this because of this math:>

 4(x-28)=100

then you multiply x and -28 by 4.

4x-112=100

then we do this:
 

4x-112=100

    +112 +112

and finally, we get this

4x = 212

But wait! There's more~~

We then divide 112 by 4, getting us a FINAL answer... of.........................................

53!
