Solution Steps

Consider the second equation. Insert the known values of variables into the equation.

$$j=\left(-2+4i\right)\left(-\frac{1}{10}-\frac{1}{5}i\right)$$

Multiply -2+4i and -\frac{1}{10}-\frac{1}{5}i to get 1.

$$j=1$$

Consider the fourth equation. Insert the known values of variables into the equation.

$$l=1$$

Consider the equation (6). Insert the known values of variables into the equation.

$$n=1$$

Consider the equation (8). Insert the known values of variables into the equation.

$$p=1$$

Consider the equation (10). Insert the known values of variables into the equation.

$$r=1$$

Consider the equation (12). Insert the known values of variables into the equation.

$$t=1$$

The system is now solved.

$$a=-\frac{1}{10}-\frac{1}{5}i j=1 k=28-96i l=1 m=28-96i n=1 o=28-96i p=1 q=28-96i r=1 s=28-96i t=1 u=28-96i$$
