Make x the subject of the equation
Make x the subject of
Notice above that by was moved as a single term.
Some equations are more difficult to rearrange. For example,
If we are trying to makethe
subject and there is more than one incidence of,
then we have to group all the's
together.
Makethe
subject of the formula
Make p the subject of
Make x the subject of
