A linear equation contains only the first power of the unknown quantity. Thus, is a linear equation.
Linear equations have only solution which is the value of the variable (in your case ) that when substituted in the equation, makes the left hand side equal to the right hand side.
A simple linear function can be written as or another identifying letter used such as . Consequently, for different values of the unknown quantity (in this case '') then the function also yields a different value.
so, your equation written as a linear equation will be:
...set it equal to zero
...replace zero with
