a system of equations
A system of linear equations.
A system of linear equations is two or more simultaneous linear equations. In mathematics, a system of linear equations (or linear system) is a collection of linear equations involving the same set of variables.
The statement "A system of linear equations is a set of two or more equations with the same variables and the graph of each equation is a line" is true.
A linear system is a set of equations involving multiple variables that can be solved simultaneously. These equations are linear, meaning they involve only variables raised to the first power and do not have any exponents or other non-linear terms. Solving a linear system involves finding values for the variables that satisfy all of the equations in the system at the same time. This process is often done using methods such as substitution, elimination, or matrix operations.
true
The idea is to work with the same variables, but it is possible that some of the variables are missing in some of the equations.
Yes, a system of linear equations can have no solution, which occurs when the equations are inconsistent. This typically happens when the lines represented by the equations are parallel, meaning they have the same slope but different y-intercepts. As a result, they never intersect, indicating that there are no values for the variables that satisfy all equations simultaneously.

If you know matrix algebra, the process is simply to find the inverse for the matrix of coefficients and apply that to the vector of answers. If you don't: You solve these in the same way as you would solve a pair of simultaneous linear equations in two unknowns - either by substitution or elimination. For example, change the subject of one of the equations to express one of the variables in terms of the other two. Substitute this value into the other two equations. When simplified, you will have two linear equations in two variables.
A set of equations that have the same variables refers to a group of mathematical equations that share one or more common variables. For example, consider the equations (2x + 3y = 6) and (4x - y = 5); both involve the variables (x) and (y). Such sets are often analyzed to find solutions that satisfy all equations simultaneously, typically through methods like substitution or elimination. These equations can represent various relationships or constraints within a given problem.
Linear Algebra is a branch of mathematics that enables you to solve many linear equations at the same time. For example, if you had 15 lines (linear equations) and wanted to know if there was a point where they all intersected, you would use Linear Algebra to solve that question. Linear Algebra uses matrices to solve these large systems of equations.
They are not. An inequality cannot, by definition, be the same as an equation.
