Why do you isolate the variable on one side the the equation when solving a linear equation?

Isolating a single variable in terms of the rest of the equation provides a solution to that variable. That is, if you know the equation that equals the variable, then you can figure out its value.


How do you know when an equation has no solution?

By solving the equation. If you get some contradictory equation, the original equation has no solution, assuming you did everything correctly. For example, if you solve:x + 3 = x + 2 by subtracting x on both sides, you get: 3 = 2 which is always false (regardless of the value of "x").


Why is it possible to check the solution to any equation?

If you found the value of x that is a solution to an equation, you want to substitute that value back into the original equation, to check that it indeed satisfies the equation. If it does not satisfy the equation, then you made an error in your calculations, and you need to rework the problem.


What is the meaning of solution of an equation?

The solution to an equation consists of the value (or values) of all the variables such that the equation is true when the variable(s) take those values.


The solution to x equals -8?

x = -8 already is a solution. If an equation has been changed until the value of x is found, and this value is accurate to the original equation, then the equation has been solved.
