According to Le Chatelier's principle:
'When a change is made to an equilibrium system, it adjusts itself to counteract the imposed change'
Eg. 1. If pressure is applied to the equilibrium mixture, equilibrium tries to elevate it by favoring the reaction which will increase the number of particles, and the number of collisions which occur in the reaction vessel, which is pressure.
Eg. 2. If the temperature of the equilibrium mixture rises, equilibrium will work in such a way to take away heat from it or absorb it. This can be achieved by favoring the endothermic reaction.

Let's say you had two glasses of water connected by a hose at the bottom. If you dump water in one glass what happens? it flows to the other side so both glasses are equal. Think of one glass as the products and one as the reactants while the hose is the equlibtium arrow. Same with chemical equations!!!!

If you dump some more anything on one side of an equation it will shift to the other side so that it's at equilibrium(rate of forward and reverse reaction are the same) 

This means if you take out some chemical from the products it will shift towards that side to equalize it just like if you take out water (from the system I talked about in the beginning) it will flow to that side you just took water out of to equalize the total system. Sooooo as an example 

$$HA + H_2O \leftrightarrow H_3O^+ +A^-$$

"A" just stands for some random acid. If I were to put more HA in this system it would flow to the products side to equalize it just like my water scenario. Or if I removed some A- the same thing would happen it would shift right and create more h3o and A- to compensate. If I added A- it would shift left to compensate for the extra A- i just added. Does this help?
