Using technology, matrices provide an efficient way to solve equations, especially multiple equations having many variables. This is true because in any system of equations written as matrix multiplication, Ax = B, the equation can be solved for x as, where matrix A is the coefficient matrix, , and matrix B is the constant matrix, .
