Linear Equation of One Variable
An equation of one variable where the variable have unit power is called a linear equation(LE).
Example:
2x-3=8 and 3x-10=0 are both linear equations.
2x2=8 and 3x+√x=14 are not linear equations.
Remember:
In linear equation there is no square, square root, or other powers.
