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

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