Introduction to Linear Equations

 

 

 

 

We know that Arithmetic expressions aremathematical expressions that are made up of numbers.

Algebraic expressions are made up of variables and numbers.
Algebraic expressions with degree one are calledlinear expressions.
All expressions that have degree greater than one are not linear.
An equation can be defined as a mathematical statement that uses symbols to express equality betweenmathematical expressions.

The expression on the left of the equality sign is the ‘LHS’ of the equation, while that on the right is its ‘RHS.
The value for which the LHS and RHS of an equation is called the Solution of the equation.
An algebraic equation can be solved by performing mathematical operations such as  and  to both sides of theequation or by transposing a number to the other side and performing the opposite operation on the number so transposed.
A linear equation may have a rational number as its solution.

 

 

A linear equation in one variable may have variableson both sides of the equation.
While solving the linear equations Numbers andVariables can be transposed from one side of anequation to the other side of the equation.

Using Linear Equations we can solve word problems 
For solving a Non-Linear Equation we have to reduce the Non Linear Equation into  a linear Equation
