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:
$$7 x = - 11 y - 8$$
Divide both parts of the equation by 7
We get the answer: x = -8/7 - 11*y/7
7*x+11*y = -8
Looking for similar summands in the left part:
7*x + 11*y = -8
Move the summands with the other variables
from left part to right part, we given:
$$7 x = - 11 y - 8$$
Divide both parts of the equation by 7
x = -8 - 11*y / (7)
We get the answer: x = -8/7 - 11*y/7

$$x_{1} = - \frac{11 \operatorname{re}{\left(y\right)}}{7} - \frac{11 i \operatorname{im}{\left(y\right)}}{7} - \frac{8}{7}$$
x1 = -11*re(y)/7 - 11*i*im(y)/7 - 8/7
