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:
$$- 20 x = 16 - 14 y$$
Divide both parts of the equation by -20
We get the answer: x = -4/5 + 7*y/10
-20*x+14*y = 16
Looking for similar summands in the left part:
-20*x + 14*y = 16
Move the summands with the other variables
from left part to right part, we given:
$$- 20 x = 16 - 14 y$$
Divide both parts of the equation by -20
x = 16 - 14*y / (-20)
We get the answer: x = -4/5 + 7*y/10

$$x_{1} = \frac{7 \operatorname{re}{\left(y\right)}}{10} + \frac{7 i \operatorname{im}{\left(y\right)}}{10} - \frac{4}{5}$$
x1 = 7*re(y)/10 + 7*i*im(y)/10 - 4/5
