When an equation graphed creates a straight line, it is called linear equations. Following is an example of linear equation for a better understanding.
5 taken from x gives 9
So x = 9 + 5 = 14
Hence x = 14
For verification of the statement,
x - 5 = 9
14 - 5 = 9
9 = 9 So left hand side value is equal to right hand side value.
Hence the value of x determined is correct.
