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:
$$- 7 x = 4 - 19 y$$
Divide both parts of the equation by -7
We get the answer: x = -4/7 + 19*y/7
-7*x+19*y = 4
Looking for similar summands in the left part:
-7*x + 19*y = 4
Move the summands with the other variables
from left part to right part, we given:
$$- 7 x = 4 - 19 y$$
Divide both parts of the equation by -7
x = 4 - 19*y / (-7)
We get the answer: x = -4/7 + 19*y/7

$$x_{1} = \frac{19 \operatorname{re}{\left(y\right)}}{7} + \frac{19 i \operatorname{im}{\left(y\right)}}{7} - \frac{4}{7}$$
x1 = 19*re(y)/7 + 19*i*im(y)/7 - 4/7
