identity
It's the value that when substituted in for the variable, makes the equation true. Ex: x + 1 = 3 The value 2, when substituted for the variable x, makes the equation true.
solution
That's the "solution" of the equation.
a solution
Substitute that value in the equation, and then check to see if the resulting statement is TRUE.
how about X = X
An identity.
No, it's the other way round - an equation that's true for every value of the variable(s) is called an identity. Of course, an identity is also an equation.
legal equation * * * * * In mathematics, it is called an identity.
If this value a satisfy the equation, then a is a solution for that equation. ( or we can say that for the value a the equation is true)
Any number that makes an equation true is a 'solution of an equation'. it is a solution
Such a value is said to be a solution, or a root, of the equation.
Such an equation is called an IDENTITY.
It's the value that when substituted in for the variable, makes the equation true. Ex: x + 1 = 3 The value 2, when substituted for the variable x, makes the equation true.
when you find the value, you SOLVED the equation. you CHECK the equation when you substitute the value in the variables place and check that the equation is true.
solution
A value of the variable that makes the equation statement true is called a solution. For example, in the equation ( x + 2 = 5 ), the value ( x = 3 ) is a solution because substituting it into the equation yields a true statement. There can be multiple solutions or none, depending on the equation. To find a solution, you can isolate the variable and solve for its value.
