Yeah, I have. Everyone does. I know some algebra cuz im in 8th grade, but yeah, I learned integers and many more since the beginning of this year and I know how to find the value. Like for example y x 9 = 54. You just find what number times 9 equal 54. Of course the answer is 6. y = 6 x 9 = 54. That was easy, but it can get trickier. Try your best and not give up. I hope you understand.
