Final answer:
The given matrix represents a system of 2 equations with 3 variables.
Step-by-step explanation:
The given matrix represents a system of equations.
Let's label the given matrix A:
A = [7 0 10]
[1 4 3]
The number of rows in matrix A represents the number of equations in the system. In this case, there are 2 rows, so we have 2 equations. The number of columns in matrix A represents the number of variables in the system. In this case, there are 3 columns, so we have 3 variables. Therefore, the given matrix represents a system of 2 equations with 3 variables.
