Displacement reaction :
A single-displacement reaction, also known as a single-replacement reaction, is a reaction by which one (or more) element(s) replaces an/other element(s) in a compound. It can be represented generally as:
A+B−C→A−C+B
All simple metal with acid reactions are single displacement reactions. For example, the reaction between magnesium, Mg, and hydrochloric acid, HCl, forms magnesium chloride, MgCl2, and hydrogen, H2.
Mg(s)+2HCl(aq)→MgCl2(aq)+H2(g)
Decomposition reaction :
A decomposition reaction is a type of chemical reaction where one reactant yields two or more products.
The general form for a decomposition reaction is
AB→A+B
Water can be separated by electrolysis into hydrogen gas and oxygen gas through the decomposition reaction: 2H2O → 2H2 + O2
Another example is the spontaneous decomposition of hydrogen peroxide into water and oxygen: 2H2O2 → 2H2O + O2
The decomposition of potassium chlorate into potassium chloride and oxygen is yet another example: 2KClO3 → 2KCl + 3O2
Combination reaction :
A combination reaction (also known as a synthesis reaction) is a reaction where two or more elements or compounds (reactants) combine to form a single compound (product). Such reactions may be represented by equations of the following form : X + Y → XY.
Formation of calcium oxide by the combination elements calcium and oxygen. 2Ca + O2 → 2CaO
Formation of ammonia by the combination of elements nitrogen and hydrogen. N2 + 3H2 → 2NH3

linear equations in two variables.
1) Age of Sohan an Ram Together is 20 years
x = Age of Sohan
y = Age of Ram
x + y = 20
2 ) Age of Ram after 2 years will be Equal to sohan age
=> x + 2 = y
