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:
$$- 18 x = - 15 y - 14$$
Divide both parts of the equation by -18
We get the answer: x = 7/9 + 5*y/6
-18*x+15*y = -14
Looking for similar summands in the left part:
-18*x + 15*y = -14
Move the summands with the other variables
from left part to right part, we given:
$$- 18 x = - 15 y - 14$$
Divide both parts of the equation by -18
x = -14 - 15*y / (-18)
We get the answer: x = 7/9 + 5*y/6

x1 = - + ------- + ---------
9 6 6
$$x_{1} = \frac{5 \operatorname{re}{\left(y\right)}}{6} + \frac{5 i \operatorname{im}{\left(y\right)}}{6} + \frac{7}{9}$$
x1 = 5*re(y)/6 + 5*i*im(y)/6 + 7/9
