The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move the summands with the other variables
from left part to right part, we given:
$$- 14 x = - 4 y - 16$$
Divide both parts of the equation by -14
We get the answer: x = 8/7 + 2*y/7
-14*x+4*y = -16
Looking for similar summands in the left part:
-14*x + 4*y = -16
Move the summands with the other variables
from left part to right part, we given:
$$- 14 x = - 4 y - 16$$
Divide both parts of the equation by -14
x = -16 - 4*y / (-14)
We get the answer: x = 8/7 + 2*y/7

$$x_{1} = \frac{2 \operatorname{re}{\left(y\right)}}{7} + \frac{2 i \operatorname{im}{\left(y\right)}}{7} + \frac{8}{7}$$
x1 = 2*re(y)/7 + 2*i*im(y)/7 + 8/7
