## Does every homogeneous system of linear equations have a solution?

Every homogeneous system has at least one solution, known as the zero (or trivial) solution, which is obtained by assigning the value of zero to each of the variables. If the system has a non-singular matrix (det(A) ≠ 0) then it is also the only solution.

## Does every homogeneous system have a non solution?

A homogeneous system of linear equations is one in which all of the constant terms are zero. A homogeneous system always has at least one solution, namely the zero vector.

**Is it possible for a system of linear equations to have no solutions?**

A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line).

### Can a homogeneous system have a non zero solution?

A nxn homogeneous system of linear equations has a unique solution (the trivial solution) if and only if its determinant is non-zero. If this determinant is zero, then the system has an infinite number of solutions.

### Can a homogeneous system have two solutions?

The possibilities for the solution set for any homogeneous system is either a unique solution or infinitely many solutions. Since the homogeneous system has the zero solution and x1=3,x2=−2,x3=1 is another solution, it has at least two distinct solution. Thus the only possibility is infinitely many solutions.

**Why do homogeneous systems always have a solution?**

Homogenous systems are linear systems in the form Ax = 0, where 0 is the 0 vector. A homogeneous system is ALWAYS consistent, since the zero solution, aka the trivial solution, is always a solution to that system. 2. A homogeneous system with at least one free variable has infinitely many solutions.

#### Which system of equation has no solution?

inconsistent system of equations

An inconsistent system of equations is a system of equations with no solution.

#### What equations have no solutions?

The constants are the numbers alone with no variables. If the coefficients are the same on both sides then the sides will not equal, therefore no solutions will occur. Use distributive property on the right side first.

**Can a homogeneous system have a non trivial solution?**

Theorem 2: A homogeneous system always has a nontrivial solution if the number of equations is less than the number of unknowns.

## Does this system have a non trivial solution How many solutions does it have?

Thus if the system has a nontrivial solution, then it has infinitely many solutions. This happens if and only if the system has at least one free variable. The number of free variables is n−r, where n is the number of unknowns and r is the rank of the augmented matrix.
