Your question could be answered with another question: Why does filling a glass from a pitcher always leave the pitcher less full? Of course the answer is that liquid has been transferred from the pitcher to the glass. The glass gets filled while the pitcher gets emptied; they always go together.
In a redox reaction it is electrons that are being transferred rather than a liquid, but the principle is the same. Reduction is giving electrons, while oxidation is receiving them. The electrons are transferred from one molecule (or atom) to another molecule (or atom) just like liquid being transferred from one container to another. One is reduced while the other is oxidized; they always go together.

In every chemical reaction there must be a balance, no matter in what aspect i.e. number of atoms, number of charge.
Hence, in redox reactions, reduction meaning when an electron is recieved or gained, there must be a place in which this electron has comes from, i.e. the reductant (the molecule, atom or compound that under goes oxidation, a loss of an or many electrons).
Therefore, to put it more correctly, every oxidation reaction is accompanied by a reduction reaction

An oxidation reaction happens while the chemical exchange of an atom or molecule is observed via a internet loss of electrons. a help reaction is the different - a internet earnings of electrons. considering that electrons, like atoms, are no longer created or destroyed in chemical reactions, an help reaction won't be able to take place without a source of electrons - that's the oxidation reaction. An oxidation reaction won't be able to take place without a help reaction via fact loose electrons are quite reactive will connect themselves to the closest atom/molecule, effecting help.

Reduction is a reaction in which electrons are accepted by the substance.The substance can gain electrons only when there is loss of electrons from another subs.So reduction & oxidation acompany with each other.

because reduction and oxidation reactions deal with charges being removed or added. and these need to balance eachother out. so if reductions taking place, something else mu st get oxidised inorder to balance the charges.

Because the electrons have to go SOME where.

because the charges have to balance out. when you take one out, you have to put one back in.
