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:
$$- 14 x = 12 y + 5$$
Divide both parts of the equation by -14
We get the answer: x = -5/14 - 6*y/7
-14*x-12*y = 5
Looking for similar summands in the left part:
-14*x - 12*y = 5
Move the summands with the other variables
from left part to right part, we given:
$$- 14 x = 12 y + 5$$
Divide both parts of the equation by -14
x = 5 + 12*y / (-14)
We get the answer: x = -5/14 - 6*y/7

$$x_{1} = - \frac{6 \operatorname{re}{\left(y\right)}}{7} - \frac{6 i \operatorname{im}{\left(y\right)}}{7} - \frac{5}{14}$$
x1 = -6*re(y)/7 - 6*i*im(y)/7 - 5/14
