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

$$x_{1} = \frac{6 \operatorname{re}{\left(y\right)}}{7} + \frac{6 i \operatorname{im}{\left(y\right)}}{7} - \frac{10}{7}$$
x1 = 6*re(y)/7 + 6*i*im(y)/7 - 10/7
