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:
$$8 x = 14 y - 14$$
Divide both parts of the equation by 8
We get the answer: x = -7/4 + 7*y/4
8*x-14*y = -14
Looking for similar summands in the left part:
-14*y + 8*x = -14
Move the summands with the other variables
from left part to right part, we given:
$$8 x = 14 y - 14$$
Divide both parts of the equation by 8
x = -14 + 14*y / (8)
We get the answer: x = -7/4 + 7*y/4

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