See, the equation is also a kind of "identity relation" but  the variable we use in the equation has specific value whereas "identity relation" is true for all values of variables.

For example, ( x +2 ) ( x +2) = x2 + 2x + 4

In above equation, if you put any value of x, then relation is true for all values of x,

such a relation is called "Identity relation"

While forming equation is any easy task,

1. Put the any variable [a,b,c, ............x,y,z] with any number with sign [multiplication, division, addition or subtraction]

2. Then, use equal axiom relating to it another number.

For example,

1. You assume the variable x with addition sign with the number 2 as x + 2

2. Then , using equal axiom with  any number like 5,

then your equation will be x +2 = 5

and the required value of x is 3.

Hope this has clear your concept of "how to form an equation".
