the answer is L= xd over y + d unfortunately i cant show the work bc i was only given the answer sorry :(
xd = y(L-d) then divide by "y" xd/y = L - d then add "d" xd/y + d = L
To solve for x in the equation x d = y ( L − d ) , you need to rearrange the equation to isolate x on one side. After distributing and rearranging, you find x = d y ( L − d ) .
