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:
$$12 x = 14 y + 20$$
Divide both parts of the equation by 12
We get the answer: x = 5/3 + 7*y/6
12*x-14*y = 20
Looking for similar summands in the left part:
-14*y + 12*x = 20
Move the summands with the other variables
from left part to right part, we given:
$$12 x = 14 y + 20$$
Divide both parts of the equation by 12
x = 20 + 14*y / (12)
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
