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

x1 = - -- + -------- + ----------
17 17 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
