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:
$$11 x = 20 y - 10$$
Divide both parts of the equation by 11
We get the answer: x = -10/11 + 20*y/11
11*x-20*y = -10
Looking for similar summands in the left part:
-20*y + 11*x = -10
Move the summands with the other variables
from left part to right part, we given:
$$11 x = 20 y - 10$$
Divide both parts of the equation by 11
x = -10 + 20*y / (11)
We get the answer: x = -10/11 + 20*y/11

10 20*re(y) 20*I*im(y)
x1 = - -- + -------- + ----------
11 11 11
$$x_{1} = \frac{20 \operatorname{re}{\left(y\right)}}{11} + \frac{20 i \operatorname{im}{\left(y\right)}}{11} - \frac{10}{11}$$
x1 = 20*re(y)/11 + 20*i*im(y)/11 - 10/11
