what is homogeneous linear equation &nonhomogeneous linear equation?what is consistence&incossistence?
A homogeneous system of linear equations is of the form below for two variables
i.e the values of the variables when substituted into any of the equation give zero.
However, non-homogeneous system of linear equations is of the form
where both are non-zero.
For three variables, homogeneous system of linear equations is of the form
while a form of non-homogeneous system of linear equations is
If any of the above systems of equations has a solution then such a system of equations is said to be consistent. If the system of equations does not have solution, then the system is inconsistent.
Consider the equations below
x and y cannot cancel out due to the reoccurrence of the first equation in the second equation. i.e.
So it's inconsistent.
However, the equations below are consistent.
Because x=2 and y=3.
