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:
$$7 x = 12 - 19 y$$
Divide both parts of the equation by 7
We get the answer: x = 12/7 - 19*y/7
7*x+19*y = 12
Looking for similar summands in the left part:
7*x + 19*y = 12
Move the summands with the other variables
from left part to right part, we given:
$$7 x = 12 - 19 y$$
Divide both parts of the equation by 7
x = 12 - 19*y / (7)
We get the answer: x = 12/7 - 19*y/7

$$x_{1} = - \frac{19 \operatorname{re}{\left(y\right)}}{7} - \frac{19 i \operatorname{im}{\left(y\right)}}{7} + \frac{12}{7}$$
x1 = -19*re(y)/7 - 19*i*im(y)/7 + 12/7
