We associate a sequence of Toeplitz matrices with the rational formal power series $T(z)$. An algorithm for solving linear equations with a Toeplitz matrix from this ...

Combination of real and imaginary parts (CRI) works well for solving complex symmetric linear systems. This paper develops a generalization of CRI method to determine the solution of Sylvester matrix ...

Some equations have letters on each side of the equals sign, for example: \(4(k + 7) = 12k - 4\). Solve this equation by rearranging all the letters onto one side of the equation and all numbers onto ...

Solve the equation \(5(2c - 3) = 19\). The equation contains a set of brackets. The easiest way to solve equations with brackets is to expand the brackets. \(\text{Area of a rectangle} = \text{base} ...
