you have to solve the actual equation in order to answer this about your variable
not always but most of the time yes

Such an equation is called an IDENTITY.
Answer 1 == In an open sentence (an equation or inequality with a variable in it), when a number replacing the variable makes the sentence true, then it is a solution.
A number that makes an equation true is its solution.
Any number that makes an equation true is a 'solution of an equation'. it is a solution
The solution set is the answers that make an equation true. So I would call it the solution.
A solution or root makes a true statement when substituted in an equation.
The solution
It's callled the "solution" of the equation.
you have to solve the actual equation in order to answer this about your variable
It is one of a set of solutions.
not always but most of the time yes
A number that makes an equation true is a solution. If there is more than one answer to an equation (such as an equation like): (x-2)(x+4)=0 then it is called a solution set (and in this case would be x={-4, 2}).
Solution. A solution of an equation is a number that satisfy the equation. This means that if you replace this number on the equation and check it, the equation will be true. When you solve an equation you can find some roots, but not all of them satisfy the equation. Thus always check your answers after resolving your equation, and eliminate as solution the answers that don't make the equation true or undefined.
