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