I'm assuming that the question is asking to find the answer to (x + 25)/x = 10
To find the answer you must first multiply both sides by x to remove the denominator of x in the fraction, leaving you with x + 25 = 10x
Next, subtract x from both sides in order to get all your x's on the same side: 25 = 9x
Lastly, just divide both sides by 9 to remove the coefficient of x, leaving you with an answer of x = 25/9 or 2 7/9
