What are Linear Equations in one variable ??

Simple Equations in one variable is a condition wherein , algebraic expressions are expressed with an equal sign with only one variable (x or y or z) in Linear equation.

Lets see an example for some simple equations

3x + 5 = 11 

In the above equation note the following

• 3x is algebraic expression
• X is variable (only 1 variable)
• The power of variable is 1.
• Change in variable value changes result of equation.( Equation holds true or not)

Lets solve a few equations

Q.1    5(x+1) = 6

Ans :   5*x + 5*1 = 6

            5x + 5 = 6

            Substracting 5 on both sides

            5x + 5 – 5 = 6 -5

           5x = 1
