A system of equations is a set of two or more equations that contain the same variables. The solution to the system is the set of values for the variables that make all of the equations true at the same time.
There are a few methods for solving a system of equations, including substitution, elimination, and graphing. Each method involves manipulating the equations to eliminate a variable and then solving for the remaining variables.
Yes, a system of equations can have one, zero, or infinitely many solutions. This depends on the relationship between the equations and how many unique values can satisfy all of the equations at the same time.
A consistent system of equations has at least one solution, meaning the equations intersect at one point. An inconsistent system of equations has no solutions, meaning the equations do not intersect at any point.
Systems of equations are commonly used in various fields of science, such as physics, engineering, and economics, to model and solve real-world problems. They can be used to determine unknown quantities or relationships between variables.
