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:
$$- 15 x = - 18 y$$
Divide both parts of the equation by -15
We get the answer: x = 6*y/5
-15*x+18*y = 0
Looking for similar summands in the left part:
-15*x + 18*y = 0
Move the summands with the other variables
from left part to right part, we given:
$$- 15 x = - 18 y$$
Divide both parts of the equation by -15
x = -18*y / (-15)
We get the answer: x = 6*y/5

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