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:
$$14 x = - 16 y - 3$$
Divide both parts of the equation by 14
We get the answer: x = -3/14 - 8*y/7
14*x+16*y = -3
Looking for similar summands in the left part:
14*x + 16*y = -3
Move the summands with the other variables
from left part to right part, we given:
$$14 x = - 16 y - 3$$
Divide both parts of the equation by 14
x = -3 - 16*y / (14)
We get the answer: x = -3/14 - 8*y/7

$$x_{1} = - \frac{8 \operatorname{re}{\left(y\right)}}{7} - \frac{8 i \operatorname{im}{\left(y\right)}}{7} - \frac{3}{14}$$
x1 = -8*re(y)/7 - 8*i*im(y)/7 - 3/14
