An equation of one variable and of first order (i.e., its highest power is one) is called a Linear equation in one variable.
Such an equation has only one solution. A solution is also called the 'root' of the given equation.

Solving linear equations in one variableFor ExampleSolve X/4 - (X-3)/6 = 1
Solution:
Multiplying throughout by the LCM of the denominators (which is 12):
3x - 2 (x - 3) = 12
3x - 2x + 6 = 12
x = 12 - 6
x = 6

A linear graph shows a linear equation in which the value of one variable depends on the value of the other variable.
It is a linear equation in one variable, a.
Solving a one variable linear equation involves getting the variable on one side of the equals sign by itself. To do this one uses the properties of numbers.
Equations can be classified according to the highest power of the variable. Since the highest power of the variable in a linear equation is one, it is also called a first-order equation.
