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
