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:
$$13 x = 11 y - 10$$
Divide both parts of the equation by 13
We get the answer: x = -10/13 + 11*y/13
13*x-11*y = -10
Looking for similar summands in the left part:
-11*y + 13*x = -10
Move the summands with the other variables
from left part to right part, we given:
$$13 x = 11 y - 10$$
Divide both parts of the equation by 13
x = -10 + 11*y / (13)
We get the answer: x = -10/13 + 11*y/13

10 11*re(y) 11*I*im(y)
x1 = - -- + -------- + ----------
13 13 13
$$x_{1} = \frac{11 \operatorname{re}{\left(y\right)}}{13} + \frac{11 i \operatorname{im}{\left(y\right)}}{13} - \frac{10}{13}$$
x1 = 11*re(y)/13 + 11*i*im(y)/13 - 10/13
