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:
$$17 x = 10 - 18 y$$
Divide both parts of the equation by 17
We get the answer: x = 10/17 - 18*y/17
17*x+18*y = 10
Looking for similar summands in the left part:
17*x + 18*y = 10
Move the summands with the other variables
from left part to right part, we given:
$$17 x = 10 - 18 y$$
Divide both parts of the equation by 17
x = 10 - 18*y / (17)
We get the answer: x = 10/17 - 18*y/17

$$x_{1} = - \frac{18 \operatorname{re}{\left(y\right)}}{17} - \frac{18 i \operatorname{im}{\left(y\right)}}{17} + \frac{10}{17}$$
x1 = -18*re(y)/17 - 18*i*im(y)/17 + 10/17
