This is an example of one of my algebraic problems. The 21st century skills I used on this was thinking and problem solving. I had to see the problem and I had to figure out how to solve it. I looked at the problem and figured out I have to first eliminate the fraction by multiplying it by itself and on each side. The thing I was most proud of was getting a lot of problems right. I improved my problem solving skills by using my brain to figure out the problem. The most difficult thing was figuring out how to get the second part of the equation, I had to change a number to a negative. If I could redo this I would pay more attention on how to solve the second part of the equation. I have done problems in the past where I had to get the answer for X. I can use this math for future lessons.
