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:
$$- 10 x = 14 y - 7$$
Divide both parts of the equation by -10
We get the answer: x = 7/10 - 7*y/5
-10*x-14*y = -7
Looking for similar summands in the left part:
-14*y - 10*x = -7
Move the summands with the other variables
from left part to right part, we given:
$$- 10 x = 14 y - 7$$
Divide both parts of the equation by -10
x = -7 + 14*y / (-10)
We get the answer: x = 7/10 - 7*y/5

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