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

$$x_{1} = - \frac{7 \operatorname{re}{\left(y\right)}}{6} - \frac{7 i \operatorname{im}{\left(y\right)}}{6} - \frac{5}{3}$$
x1 = -7*re(y)/6 - 7*i*im(y)/6 - 5/3
