Can a linear system of 3 equations have exactly two solutions?

No. A system of linear equations in two variables may have zero, one, or infinitely many solutions.

Can a linear system have exactly 2 solutions?

Most linear systems you will encounter will have exactly one solution. However, it is possible that there are no solutions, or infinitely many. (It is not possible that there are exactly two solutions.) The word unique in this context means there is a solution, and it’s the only one.

Is it possible for a system of three linear equations to have one solution if so complete the possible example?

In order for three equations with three variables to have one solution, the planes must intersect in a single point. Case 2: There is no solution. The three planes do not have any points in common. (Note that two of the equations may have points in common with each other, but not all three.)

How many solutions can a system of three linear equations have?

For systems of equations in three variables, there are an infinite number of solutions on a line or plane that is the intersection of three planes in space.

Does a system with 3 equations in 3 unknowns always has a solution?

A homogeneous system of 3 linear equations in 4 unknowns always has a solution, in fact, always has a non-trivial solution, a solution where the unknowns are not all zero.

Can there be multiple solutions to a system of equations?

There can be more than one solution to a system of equations. A system of linear equations will have one point of intersection, or one solution. To graph a system of equations that are written in standard form, you must rewrite the equations in slope -intercept form.

Can a linear equation have more than one solution?

A system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs intersect at a point.
