Equation: It means equality of two algebraic expressions involving one or more variables.
Linear equation: When an equation involves only one linear polynomial, it is linear equation.
There are some rules while solving linear equations:
- We can add same number on both sides of the equation.
- We can subtract the same number from both sides of the equation.
(c) We can multiply both sides of equation by the same nonzero number.
(d) We can divide both sides of the equation by the same nonzero number.
This is known as cross multiplication.
