Given F_{1} = 10, F2_{1} = 20, Distance from F_{1} to fulcrum (x) = 5, calculate Lever Length (d)

__The Lever Equation is as follows:__

F_{1}x = F_{2}(d - x)

__Multiply the right side of the equation out:__

F_{1}x = F_{2}d - F_{2}x

__Add F___{2}x to both sides:

F_{1}x + F_{2}x = F_{2}d - F_{2}x + F_{2}x

__Cancelling F___{2}x on the right side, we get:

F_{1}x + F_{2}x = F_{2}d

__Factor out x:__

x(F_{1} + F_{2}) = F_{2}d

__Divide each side of the equation by F___{2}:

__Cancelling F___{2} on the right side, we get:

__Plug in our numbers and simplify:__

Lever Length (d) =**7.5**
