Given the equation P = 2w + 2l solve for w.
like a first step subtract from both sides 2l so what will get ?
P = 2w + 2l You must get w by itself. Subtract 2l P - 2l = 2w What do you think you should do next?
what is p?
We are just dealing with variables, it won't do anything really.
It's like if we were looking for what P equaled, that would be.
Jamal there is given that P = 2w -2l so this is P
How many w's does it say you have?
P - 2l = 2w
2
So you can divide by 2 to isolate w.
\[w = \frac{ P - 2l }{ 2 }\]
idk how to divide by 2 if i dont know what P is??
It's just a variable.
You don't need to know what they actually are, numerical wise.
so how to divide
Just by 2 to isolate w. There's 2w, so you divide by 2, and w stays isolated.
Look up a little and you will see what w equals and that's your answer.
ohh ty
