Ok, don't take what I have to say the wrong way - I really admire your love of science, and would like to encourage you to pursue it. However, having said that, at the age of 11 you are quite simply missing the mathematical basics which are needed to understand the Einstein equations, and for the same reason you shouldn't expect to be able to "decipher" them. But just to satisfy your curiosity, I will write them down for you anyway :
The quantity

is called the Einstein tensor, and roughly represents the "geometry of space-time".

is called the energy-momentum tensor, and measures everything that can be a source of gravity, such as mass, energy, stress, momentum etc etc. The

is a proportionality constant. The "tensors" in this equation have subscripts because they are in fact a collection of different components; each subscript runs from 0...3, so what looks like one equation above is really just shorthand for a system of many equations.
What this equation tells us is thus that the geometry of space-time is determined by the presence of energy-momentum; in other words - gravity is just a manifestation of geometry ( and
not a force, as in good old Newtonian mechanics ), which is in turn determined by things like mass, energy, momentum etc etc. Given your young age I wouldn't bother trying to understand the underlying mathematics, but if you get the basic idea, then you already know more than most kids your age
