A scale like the one shown is balanced when it has 18 1-pound bricks on one side and 3 equally sized pieces of gold on the other. How much does each piece of gold weigh?

Let each piece of gold weigh x lbs.  And we have that


1 8 * 1   =  3 * x


And it's clear that each piece of gold must weigh 6 lbs



cool cool cool
