It is any equation which is not an identity.
An equation has an equal = sign whereas an expression does not.
hyperbola
Both are same..just the names are different.
Equation: x+3=3+x (notice the equal sign: equal; equation)Expression: x+3 (notice no equal sign)
identity is a special information related to a particular person and equation is a way of writing a formula with the sign (=)
Conditional love has conditions, while emotional love does not.
Conditional - Imposing, depending on, or containing a condition. Unconditional - without conditions or limitations.
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.
Expression has no answer. a equation has an answer
one is conditional (even IF) and one is not.
An equation can lead to a solution.
an equation has an equals sign.
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.
Root means solution in this context.
