Question

Describe the process of isolating a variable in a formula.In your opinion, what is the greatest advantage in isolating a variable in a formula? Describe the process in general terms first( outline the steps). Then, mention how earlier concepts apply to this process ( for example, additive and multiplicative inverses.)
Give an example that shows each step in the process. In physics , many equations contain multiple variables and we can often solve for each one.
For example a famous equation is: E= mc2
This tells us that energy ( E) equals mass ( m) times the speed of light squared ( c2)
Energy = mass*( speed of light)* ( speed of light)
We can solve the equation for m by dividing by c2 on both sides to get m= E/ c2
How would you isolate the variable y in the equation xy=1? What x value should we be careful about plugging in?
How would you isolate z in the equation zx-yz=1? Is there any restriction on the values we can plug in for x and y?
