How do we use and transform formulas for particular variables?
If you want to get a particular variable you will have to solve around the other numbers or variables. For example, if a question says solve for y and the equation is 3y+9=3x+21, you will have to get y by itself. In order to get y by itself you will have to subtract 9 because you have to do the opposite Then you will get 3y=3x+12. Then you will have to divide by 3 to get y by itself. Then you will have y=1x+4. That is what you will have to do to get particular variables.
