They often arise in the context of linear systems ... Similarly, an inversion-free method was introduced for solving nonlinear matrix equations, which avoids the computational burden of matrix ...

To solve the equation, inverse the operations. The opposite of dividing by 4 is multiplying by 4. Any operation must be applied to both sides of the equation, so multiply both sides by 4.
