<PRE><B>Question 793650</B>
What number when decreased by 24 is twice itself?

representation:
let x be the number


solution:

     24-x=2x
     
combine like terms:
     -x-2x=-24
       -3x=-24

divide -3 from both side
       -3x/-3=-24/-3
            x=8
     
answer: the number that decrease in 24 is twice itself is 8


checking:   24-x=2x
            24-8=2(8)
              16=16

      this prove the answer///</PRE>
