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:
$$- 11 x = 3 y + 14$$
Divide both parts of the equation by -11
We get the answer: x = -14/11 - 3*y/11
-11*x-3*y = 14
Looking for similar summands in the left part:
-11*x - 3*y = 14
Move the summands with the other variables
from left part to right part, we given:
$$- 11 x = 3 y + 14$$
Divide both parts of the equation by -11
x = 14 + 3*y / (-11)
We get the answer: x = -14/11 - 3*y/11

$$x_{1} = - \frac{3 \operatorname{re}{\left(y\right)}}{11} - \frac{3 i \operatorname{im}{\left(y\right)}}{11} - \frac{14}{11}$$
x1 = -3*re(y)/11 - 3*i*im(y)/11 - 14/11
