Question 105464


{{{P=21+2w}}} Start with the given equation




{{{0=21+2w-P}}}Subtract P from both sides



{{{-2w=21-P}}} Subtract 2w from both sides



{{{w=(21-P)/(-2)}}} Divide both sides by -2 to isolate w



--------------------------------------------------------------

Answer:

So our answer is {{{w=(21-P)/(-2)}}}
