Question 596031: Hello, I am trying to solve this equation for my son who is in high school. He is having a difficult time with algebra and it's been a while since I've touched on this subject.I would greatly appreciated if someone could help us both out. The equation is 2y - 3(2 - y) = 5 + y . Thank you, and if you can show the steps on how this is done instead of just the answer would also be great so that I may in the future be of some help and can learn myself as well.

Question 597900: 23 - y = 53= I know you can subtract 23 from left side and have -y by itself. do you add 23 to the right side and now have -y =76. I know somehow you either multiply -y to both sides or divide both sides by -y or times it by -1. I can't remember. I do need to know when you subtract a number fron one side, you add it to the other side. Correct? How would you do this problem?
