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:
$$- 8 x = - 15 y - 12$$
Divide both parts of the equation by -8
We get the answer: x = 3/2 + 15*y/8
-8*x+15*y = -12
Looking for similar summands in the left part:
-8*x + 15*y = -12
Move the summands with the other variables
from left part to right part, we given:
$$- 8 x = - 15 y - 12$$
Divide both parts of the equation by -8
x = -12 - 15*y / (-8)
We get the answer: x = 3/2 + 15*y/8

$$x_{1} = \frac{15 \operatorname{re}{\left(y\right)}}{8} + \frac{15 i \operatorname{im}{\left(y\right)}}{8} + \frac{3}{2}$$
x1 = 15*re(y)/8 + 15*i*im(y)/8 + 3/2
