Question

A number minus 25 is equal 51

Answer 1

A number (x) minus 25 (-25) is equal to (=) 51 (51).
Rewrite everything only in parenthesis.
x - 25 = 51

Now, we can solve.

To solve for x, we need for it to be on one side by itself. However, x is subtrating 25. To get rid of -25, we must perform the opposite order of operations.

Remember, what you do to one side of an equation, you must do to the other.

Add 25 to both sides.
-25 + 25 = 0
51 + 25 = 76.

We are now left with:
x = 76.

I hope this helps!

Answer 2

  x − 25 = 51 .

 This is the expression that would be written; in which "x" refers to the particular number.

To solve for that number, one would add 25 to EACH SIDE of the equation; to isolate "x" (the particular number to be solved for) on ONE SIDE of the equation; and to solve for "x" (that particular number) ; AS FOLLOWS:
_________________________________
   x − 25 = 51 ;

  Add 25 to each side of the equation; 

  x − 25 + 25 = 51 + 25 ;

   to get: 
 
            x = 76.

The particular number is:  " 76 " .
