Question

Solve P = 2w + 2h for w.

Answer 1

You are trying to find the perimeter.

Answer 2

w=P1/2-h

Answer 3

So since we can't actually solve for 'w' because we have too many unknowns...what we would do...is isolate 'w'....w = .....

So

P = 2w + 2h

Subtract 2h from both sides...

P - 2h = 2w

Now divide both sides by 2....because this will leave just 'w'

\[w = \frac{ 1 }{ 2 }P - h\]
