Solving for a letter?

Question

I need help solving this. I really have trouble solving for a letter. Here is the problem. Thanks in advance.

s=2Lh+2Lw+2wh, solve for L.

Answer 1

s = 2Lh + 2Lw + 2wh

First get everything without an L on one side:

s - 2wh = 2Lh + 2Lw

Now, factor out the L:

s - 2wh = L(2h + 2w)

Now divide both sides by the stuff next to the L:

(s - 2wh) / (2h + 2w) = L

Answer 2

There's a couple ways. One is substitution- get the problem so that one variable is alone on one side. So you have s=50+2f. Then, since you know that s is the same as 50+2f substitute that back into the original equation. So instead of 4f+2s=100 you have 4f+2(50+2f)=100. Then once you figure out what f is, you can substitute that into the original equation and solve for s. Hope that helps!

Answer 3

s/2= Lh + Lw + wh
s/2 - wh = L (h +w)
[s/2 -wh]/ (h + w) = L


send word if you need more steps

Answer 4

2L(h+w) = s-2wh
L = (s-2wh)/2(h+w)
