What is a code to solve the Linear Equation of Single Variable and the other steps required given the following:
Solve the Linear Equation of Single Variable | def to solve the given equation.
Traverse the equation.
For cases such as : x , - x , + x.
Flip sign once ' = ' is seen.
There may be a number left in the end.
For infinite solutions.
For no solution.
x = total sum / coeff of x ' - ' sign indicates moving numeric value to right hand side.
Driver code"
