12x+6y=9 - 1

4x+2y=0 - 2

y=-2x

sub y= -2x into 1,

12x+6(-2x)=9

12x-12x=9

0=9

thus, no solution.

Q: What is the solution of the following linear system 12x plus 6y equals 9 4x plus 2y equals 0?

yes it is possible for a system of two linear inequalities to have a single point as a solution.

It can happen. Then there is no solution!It can happen. Then there is no solution!It can happen. Then there is no solution!It can happen. Then there is no solution!

In linear algebra, Cramer's rule is an explicit formula for the solution of a system of linear equations with as many equations as unknowns, valid whenever the system has a unique solution.

A system of linear equations can only have: no solution, one solution, or infinitely many solutions.

A system of linear equations that has at least one solution is called consistent.
