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:
$$- 13 x = - 10 y - 8$$
Divide both parts of the equation by -13
We get the answer: x = 8/13 + 10*y/13
-13*x+10*y = -8
Looking for similar summands in the left part:
-13*x + 10*y = -8
Move the summands with the other variables
from left part to right part, we given:
$$- 13 x = - 10 y - 8$$
Divide both parts of the equation by -13
x = -8 - 10*y / (-13)
We get the answer: x = 8/13 + 10*y/13

8 10*re(y) 10*I*im(y)
x1 = -- + -------- + ----------
13 13 13
$$x_{1} = \frac{10 \operatorname{re}{\left(y\right)}}{13} + \frac{10 i \operatorname{im}{\left(y\right)}}{13} + \frac{8}{13}$$
x1 = 10*re(y)/13 + 10*i*im(y)/13 + 8/13
