if 25 is added to three times a number the result is 70.find the number?

math 
Ms. Sue,
25 + 3x = 70
How do you think you'll solve this equation?
Cody, I've asked you similar questions before, and you haven't responded. Why? 
math 
marissa,
you subtract 25 from each side of the equation to get 3x=45. then you divide each side by 3 to get x=15. your just undoing the math
