Two boys want to use a seesaw, and they need to move the seesaw so that their weights will balance out. The formula is given by w1 • d1 = w2 • d2 where w1 = weight of the first boy, d1 = distance of the first boy from the fulcrum, w2 = weight of the second boy, and d2 = distance of the second boy from the fulcrum. Rewrite the formula to solve for d2. Show all steps in your work.

    w1 . d1 = w2 . d2 divide both sides by w2 and you have it.

    Oh ok that's not that hard at all so u understand when one thing multiplies on one side it divides on other

    Which means d2 must be left alone in one side so you w2 is multiplying by d2 just divide it in the other side

    No you won't get 1=4 you will get d2= ( w1 times d1)/ w2

    \[w _{1}\times d _{1}=w _{2}\times d _{2}\]divide both sides by w2 u get-\[\frac{ (w _{1} \times d _{1}) }{ w _{2} }=d _{2}\]
