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:
$$20 x = 7 - 6 y$$
Divide both parts of the equation by 20
We get the answer: x = 7/20 - 3*y/10
20*x+6*y = 7
Looking for similar summands in the left part:
6*y + 20*x = 7
Move the summands with the other variables
from left part to right part, we given:
$$20 x = 7 - 6 y$$
Divide both parts of the equation by 20
x = 7 - 6*y / (20)
We get the answer: x = 7/20 - 3*y/10

20 10 10
$$x_{1} = - \frac{3 \operatorname{re}{\left(y\right)}}{10} - \frac{3 i \operatorname{im}{\left(y\right)}}{10} + \frac{7}{20}$$
x1 = -3*re(y)/10 - 3*i*im(y)/10 + 7/20
