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:
$$2 x = 20 y - 7$$
Divide both parts of the equation by 2
We get the answer: x = -7/2 + 10*y
2*x-20*y = -7
Looking for similar summands in the left part:
-20*y + 2*x = -7
Move the summands with the other variables
from left part to right part, we given:
$$2 x = 20 y - 7$$
Divide both parts of the equation by 2
x = -7 + 20*y / (2)
We get the answer: x = -7/2 + 10*y

x1 = -7/2 + 10*re(y) + 10*I*im(y)
$$x_{1} = 10 \operatorname{re}{\left(y\right)} + 10 i \operatorname{im}{\left(y\right)} - \frac{7}{2}$$
x1 = 10*re(y) + 10*i*im(y) - 7/2
