Homework Help: Rewriting again

  1. Oct 4, 2006 #1
    I know you all are probably sick of me posting these kind of "easy" problems, but rewriting equations is one of those things that I just seem to struggle with. So that being said, can I get help with [tex]2A=h(b_{1}+b_{2})[/tex]? I need to solve for [tex]b_{1}[/tex]. Maybe if someone just gave me the first step, I could get the rest ???

    [tex] 2A=h(b_{1}+b_{2}) [/tex].
    [tex] 2A = hb_{1}+hb_{2} [/tex].
    [tex] 2A-hb_{2} = hb_{1} [/tex].

    So how would you solve for [tex] b_{1} [/tex]?

    Wouldn't you divide both sides by h?
  5. Oct 4, 2006 #4
    yes you would.

    So the final answer would be [tex]\frac{2A-b_{2}}{h}=b_{1}[/tex] ?

    no it would be [tex] b_{1} = \frac{2A-hb_{2}}{h} [/tex] or [tex] b_{1} = \frac{2A}{h} - b_{2} [/tex]

    Oh you're right, I just forgot the 2nd h in my equation.

    And thanks for all your help. I think I'm starting to get this more, so hopefully this will be my last rewriting problem!
