identity is a special information related to a particular person and equation is a way of writing a formula with the sign (=)
Expression has no answer. a equation has an answer
Three lines between two equations means that there is an identity present. This means that whatever numbers you put into the equation it will always equal the equation on the other side.
an equation has an equals sign.
An expression has no equal sign whereas an equation does have an equal sign
Difference in math means subtraction. To express the difference between 6 and 2 you would use the equation 6 - 2 = 4.
Identity: An equation satisfied by every number that is a meaningful replacement for the variable. Example: 3(X+1)=3X+3Conditional Equation: An equation that is satisfied by some number but not others, such as 2X=4

An identity equation has infinite solutions.
An equation can lead to a solution.
an equation has an equals sign.
The equation for calculating the phase difference between two waves is: Phase Difference (2 / ) (x) Where: Phase Difference is the difference in phase between the two waves is the wavelength of the waves x is the difference in position between corresponding points on the waves

Root means solution in this context.
The difference between substitution and transposition is that in:Subtitution:each letter retains its position but changes its identity,Transposition:each letter retains its identity but changes its position.
An identity is true for all values of the variable whereas an equation is true for only a finite number of values.For example,Identity: (x + 2)3 = x3 + 6x2 + 12x + 27 is true, whatever the value of x.ButEquation: x3 - x = 0 is true only when x = -1, 0 or 1.
