## octoberchick1011 Group Title Solve the equation for H: S = LW + WH + HL one year ago one year ago

S = LW + WH + HL First, get all of the elements with H on one side. S - LW = WH + HL Then factor out the H: S - LW = H(W+L) Divide both sides by (W + L) (S - LW)/(W + L) = H. You're done!

So your final answer should be $\frac{ S - LW }{ W + L }$

Thank you so much!

No problem! :) It's not a terribly difficult thing to do, although working with letter variables (or constants) instead of numbers is always more intimidating. Good luck with the rest of your math!
