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:
$$- 18 x = - 10 y - 16$$
Divide both parts of the equation by -18
We get the answer: x = 8/9 + 5*y/9
-18*x+10*y = -16
Looking for similar summands in the left part:
-18*x + 10*y = -16
Move the summands with the other variables
from left part to right part, we given:
$$- 18 x = - 10 y - 16$$
Divide both parts of the equation by -18
x = -16 - 10*y / (-18)
We get the answer: x = 8/9 + 5*y/9

8 5*re(y) 5*I*im(y)
x1 = - + ------- + ---------
9 9 9
$$x_{1} = \frac{5 \operatorname{re}{\left(y\right)}}{9} + \frac{5 i \operatorname{im}{\left(y\right)}}{9} + \frac{8}{9}$$
x1 = 5*re(y)/9 + 5*i*im(y)/9 + 8/9
