Yes, for example:
| x | = 0
with the only solution:
x = 0
A system of equations with exactly one solution intersects at a singular point, and none of the equations in the system (if lines) are parallel.
A system of equations may have any amount of solutions. If the equations are linear, the system will have either no solution, one solution, or an infinite number of solutions. If the equations are linear AND there are as many equations as variables, AND they are independent, the system will have exactly one solution.
If the equations or inequalities have the same slope, they have no solution or infinite solutions. If the equations/inequalities have different slopes, the system has only one solution.
Yes, a system of equations can have more than one solution if the equations represent the same line or plane in a geometric sense. In such cases, there are infinitely many solutions that satisfy all equations simultaneously. This typically occurs in systems of linear equations where the equations are dependent. Conversely, if the equations are independent, the system will either have a unique solution or no solution at all.
The graphs of the two equations have only one intersection point.
simultaneous equations
They will be a set of lines meeting at one point - the solution.
Provide a system of equations in slope-intercept form that has one solution. Using complete sentences, explain why this system has one solution.
It is a set of equations, which is also called a system of equations. There may be no solution, a single (unique) solution or more than one - including infinitely many.
Put the values that you find (as the solution) back into one (or more) of the original equations and evaluate them. If they remain true then the solution checks out. If one equation does not contain all the variables involved in the system, you may have to repeat with another of the original equations.
A system of equations that has at least one solution is called a consistent system. This means that the equations in the system intersect at least at one point in their graphical representation. If there is exactly one solution, the system is termed independent, while if there are infinitely many solutions, it is called dependent.
A system of linear equations can only have: no solution, one solution, or infinitely many solutions.
