Blog post week 15 solving addition and subtraction rational equations

This week I learned how to add and subtract rational expressions and how to solve for a variable value. The first step is to make the denominators the same and to do that you multiply it by the lowest common multiple, and then you multiply the top with the same denominators. In my example I show how I did that and then after that I made an equation and since it was a linear equation I had to move the variables to one side and then collect the like terms and after solve for my variable. So it was simple algebra, the only thing I found confusing was multiplying the denominators with the numerators because they had to be the same. Then slowly I understood how to do it and now have a good understanding of which denominator goes with each numerator.
