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:
$$15 x = 19 - 2 y$$
Divide both parts of the equation by 15
We get the answer: x = 19/15 - 2*y/15
15*x+2*y = 19
Looking for similar summands in the left part:
2*y + 15*x = 19
Move the summands with the other variables
from left part to right part, we given:
$$15 x = 19 - 2 y$$
Divide both parts of the equation by 15
x = 19 - 2*y / (15)
We get the answer: x = 19/15 - 2*y/15

15 15 15
$$x_{1} = - \frac{2 \operatorname{re}{\left(y\right)}}{15} - \frac{2 i \operatorname{im}{\left(y\right)}}{15} + \frac{19}{15}$$
x1 = -2*re(y)/15 - 2*i*im(y)/15 + 19/15
