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:
$$7 x = - 15 y - 11$$
Divide both parts of the equation by 7
We get the answer: x = -11/7 - 15*y/7
7*x+15*y = -11
Looking for similar summands in the left part:
7*x + 15*y = -11
Move the summands with the other variables
from left part to right part, we given:
$$7 x = - 15 y - 11$$
Divide both parts of the equation by 7
x = -11 - 15*y / (7)
We get the answer: x = -11/7 - 15*y/7

$$x_{1} = - \frac{15 \operatorname{re}{\left(y\right)}}{7} - \frac{15 i \operatorname{im}{\left(y\right)}}{7} - \frac{11}{7}$$
x1 = -15*re(y)/7 - 15*i*im(y)/7 - 11/7
