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

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