Anybody good at algebra?
Does anybody know how you would make 'k' the subject of the equation? See the pic attached. Any help would be appreciated..

I know how but it would be better if you did your own homework.
Remember what you do to one side of the = sign you do to the other side.
hint....multiply both sides by k then divide each side by "a"
k=????????/
multiply both sides by root b then turn the whole thing upside down..
Does making k the subject of the equation mean the same as solving for k? Is this the new math?
Find out what you each is asking for then do whatever it takes to get it alone on one side.
Then do the same to the other side..
In the first one you multiplied both sides by k
then divided by "a" to both sides to get k=b^2/a
Do that to the rest of them....
the answer to Q.a is the easiest, since it just involves shifting the three expressions around
Q.b is slightly more complex since it involves balancing the equation by doing some arithmetic
- remember that what you do to one side of the equation, you must also do to the other..
so - for example, taking 2 from the right side means that you also have to do the same to the left..
you are not being asked to simplify the equations - just to rearrange them..
