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:
$$- 4 x = - 18 y - 14$$
Divide both parts of the equation by -4
We get the answer: x = 7/2 + 9*y/2
-4*x+18*y = -14
Looking for similar summands in the left part:
-4*x + 18*y = -14
Move the summands with the other variables
from left part to right part, we given:
$$- 4 x = - 18 y - 14$$
Divide both parts of the equation by -4
x = -14 - 18*y / (-4)
We get the answer: x = 7/2 + 9*y/2

$$x_{1} = \frac{9 \operatorname{re}{\left(y\right)}}{2} + \frac{9 i \operatorname{im}{\left(y\right)}}{2} + \frac{7}{2}$$
x1 = 9*re(y)/2 + 9*i*im(y)/2 + 7/2
