Here the highest power of each equation is one.Ģx + 3y = 15, 7x - y/3 = 3 are equations in two variables x and y. The general form of a linear equation is ax + b = c, where a, b, c are constants and a0 and x and y are variables.įor Example: x + 7 = 12, 5/2x - 9 = 1, x 2 + 1 = 5 and x/3 + 5 = x/2 - 3 are equations in one variable x. Or we can say that a linear equation that has only one variable is called a linear equation in one variable.Ī linear equation value when plotted on the graph forms a straight line. ⇒ Don't Miss Out: Get Your Free JEE Main Rank Predictor 2024 Instantly! 🚀Īn equation in which the maximum degree of a term is one is called a linear equation. To solve an equation, we carry out a series of identical Mathematical operations on two sides of the equation such that the unknown variable is on one side and its value is obtained on the other side.Įquation: An equation is a statement of equality of two algebraic expressions involving constants and variables.īased on the degree and variable in the equations, they are classified as linear and nonlinear equations.

The equation remains unchanged if we carry out the same operation on both sides of the equation.

The LHS is given by the expression 3x + 4 and the RHS is given by the constant 8. The two sides of the equality sign are referred to as the left-hand side (LHS) and the right-hand side (RHS) of the equation.įor example, in the equation 3x + 4 = 8, where 3, 4, and 8 are the constants, and x is the variable. An equation is a statement of the equality of two expressions. We have learned about equations in the earlier classes.
