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:
$$2 x = 9 - 14 y$$
Divide both parts of the equation by 2
We get the answer: x = 9/2 - 7*y
2*x+14*y = 9
Looking for similar summands in the left part:
2*x + 14*y = 9
Move the summands with the other variables
from left part to right part, we given:
$$2 x = 9 - 14 y$$
Divide both parts of the equation by 2
x = 9 - 14*y / (2)
We get the answer: x = 9/2 - 7*y

x1 = 9/2 - 7*re(y) - 7*I*im(y)
$$x_{1} = - 7 \operatorname{re}{\left(y\right)} - 7 i \operatorname{im}{\left(y\right)} + \frac{9}{2}$$
x1 = -7*re(y) - 7*i*im(y) + 9/2
