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:
$$10 x = 15 y - 11$$
Divide both parts of the equation by 10
We get the answer: x = -11/10 + 3*y/2
10*x-15*y = -11
Looking for similar summands in the left part:
-15*y + 10*x = -11
Move the summands with the other variables
from left part to right part, we given:
$$10 x = 15 y - 11$$
Divide both parts of the equation by 10
x = -11 + 15*y / (10)
We get the answer: x = -11/10 + 3*y/2

$$x_{1} = \frac{3 \operatorname{re}{\left(y\right)}}{2} + \frac{3 i \operatorname{im}{\left(y\right)}}{2} - \frac{11}{10}$$
x1 = 3*re(y)/2 + 3*i*im(y)/2 - 11/10
