2.92 Linear and Non-Linear Equations

Linear Equations
An equation in which the highest index of the variables present is one, is called a "linear equation".
An equation with one variable and of first order (i.e., its highest power is one) is called a Linear equation. It has only one solution and is also called the 'root' of the given equation.

  • Linear Equations with One Variable:
    Examples:
    x + 8 = 10
    6x - 3 = 2x + 9
    6x - 3 = 2x + 9 can be simplified as 4x = 12

  • Linear Equations with Two Variables:
    Examples:
    x + y = 20
    In above example, there are two variables x and y, but the exponents of the variables are only one. Therefore, the equation x+y=20 is a linear equation in two variables. a + 4by = 15

  • Linear Equations with Three Variable :
    Examples:
    x + y + z = 67
    2a + 5b + 3c = 34
Non-linear Equations
Equations that have indexes are higher than 1 are called non-linear equations.
Examples:
63 - 7x - 3 = 0
x4 - 5x2 = 5
