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:
$$- 15 x = 7 y + 1$$
Divide both parts of the equation by -15
We get the answer: x = -1/15 - 7*y/15
-15*x-7*y = 1
Looking for similar summands in the left part:
-15*x - 7*y = 1
Move the summands with the other variables
from left part to right part, we given:
$$- 15 x = 7 y + 1$$
Divide both parts of the equation by -15
x = 1 + 7*y / (-15)
We get the answer: x = -1/15 - 7*y/15

$$x_{1} = - \frac{7 \operatorname{re}{\left(y\right)}}{15} - \frac{7 i \operatorname{im}{\left(y\right)}}{15} - \frac{1}{15}$$
x1 = -7*re(y)/15 - 7*i*im(y)/15 - 1/15
