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:
$$4 x = 7 y + 4$$
Divide both parts of the equation by 4
We get the answer: x = 1 + 7*y/4
4*x-7*y = 4
Looking for similar summands in the left part:
-7*y + 4*x = 4
Move the summands with the other variables
from left part to right part, we given:
$$4 x = 7 y + 4$$
Divide both parts of the equation by 4
x = 4 + 7*y / (4)
We get the answer: x = 1 + 7*y/4

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