Question

Solve for W:

P=2L+2W.

Answer 1

Take away 2L from both sides

Answer 2

you would do that because
you want to get "W" all alone
"2L" is crowding the "2W"

Answer 3

2W=P-2L?

Answer 4

yes :)
now the "2" in "2W" is crowding the "W" that we want

so how would we get rid of that 2 ? :)

Answer 5

Divide! :)

Answer 6

yes! :D

Answer 7

W=P-2L/2

Answer 8

bingo :D

Answer 9

yaaaaaay!

Answer 10

careful tho, (P-2L)/2 would be correct you need parenthesis

Answer 11

Thank you...If I simplify it, would it be W=1/2P-L, or I don't need to do that?

Answer 12

you can do that if you would like :)
either one would be correct

Answer 13
