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:
$$5 x = 14 y - 15$$
Divide both parts of the equation by 5
We get the answer: x = -3 + 14*y/5
5*x-14*y = -15
Looking for similar summands in the left part:
-14*y + 5*x = -15
Move the summands with the other variables
from left part to right part, we given:
$$5 x = 14 y - 15$$
Divide both parts of the equation by 5
x = -15 + 14*y / (5)
We get the answer: x = -3 + 14*y/5

x1 = -3 + -------- + ----------
5 5
$$x_{1} = \frac{14 \operatorname{re}{\left(y\right)}}{5} + \frac{14 i \operatorname{im}{\left(y\right)}}{5} - 3$$
x1 = 14*re(y)/5 + 14*i*im(y)/5 - 3
