Specify the variable you want to isolate.
Isolate x, using ISOL (isolate) in the SOLVE menu.
The expression returned represents a symbolic solution of the equa-
tion for x-that is, the equation
is satisfied when
Expanding and Collecting
x occurs more than once, you must manipulate the equation to
eliminate all but one occurrence of
The next example shows how to
in the equation
The strategy for this example is to expand the equation, subtract one
side's x-term from both sides, collect the equation to cancel the x-term
on one side and produce a single x=term on the other side, and then
Put the equation on the stack.
