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:
$$11 x = 2 y - 15$$
Divide both parts of the equation by 11
We get the answer: x = -15/11 + 2*y/11
11*x-2*y = -15
Looking for similar summands in the left part:
-2*y + 11*x = -15
Move the summands with the other variables
from left part to right part, we given:
$$11 x = 2 y - 15$$
Divide both parts of the equation by 11
x = -15 + 2*y / (11)
We get the answer: x = -15/11 + 2*y/11

$$x_{1} = \frac{2 \operatorname{re}{\left(y\right)}}{11} + \frac{2 i \operatorname{im}{\left(y\right)}}{11} - \frac{15}{11}$$
x1 = 2*re(y)/11 + 2*i*im(y)/11 - 15/11
