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:
$$- 10 x = 6 y + 7$$
Divide both parts of the equation by -10
We get the answer: x = -7/10 - 3*y/5
-10*x-6*y = 7
Looking for similar summands in the left part:
-10*x - 6*y = 7
Move the summands with the other variables
from left part to right part, we given:
$$- 10 x = 6 y + 7$$
Divide both parts of the equation by -10
x = 7 + 6*y / (-10)
We get the answer: x = -7/10 - 3*y/5

$$x_{1} = - \frac{3 \operatorname{re}{\left(y\right)}}{5} - \frac{3 i \operatorname{im}{\left(y\right)}}{5} - \frac{7}{10}$$
x1 = -3*re(y)/5 - 3*i*im(y)/5 - 7/10
