Solve 252x−1=400 for x.
Which answer shows the correct steps?

1.75

Step-by-step explanation:

252x-1=400

First we need to isolate the x in one side of the equation

Lets add 1 to each side of the equation to get rid of -1

252x=441

now we divide 441 by 252 to get x

x=1.75

UPDATE

The owner of the question said its supposed to be 25^2x -1 =400

ok lets do this

25^2 *  x=401

625x =401

x=.6416

41*67/2=1373.5
