For 10 points, give the term for a group of linear equations using the same variables.
The solution to these objects may be represented as a determinant of a square matrix divided by another determinant. One way to obtain a solution to them involves rewriting a matrix in reduced row echelon form. In addition to Kramer's Rule and Gaussian Elimination, another method of solving them involves substituting a variable for elimination. The point of intersection of their graphs is another representation of their solution. For 10 points, give the term for a group of linear equations using the same variables.
