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:
$$- 14 x = 14 - 16 y$$
Divide both parts of the equation by -14
We get the answer: x = -1 + 8*y/7
-14*x+16*y = 14
Looking for similar summands in the left part:
-14*x + 16*y = 14
Move the summands with the other variables
from left part to right part, we given:
$$- 14 x = 14 - 16 y$$
Divide both parts of the equation by -14
x = 14 - 16*y / (-14)
We get the answer: x = -1 + 8*y/7

8*re(y) 8*I*im(y)
x1 = -1 + ------- + ---------
7 7
$$x_{1} = \frac{8 \operatorname{re}{\left(y\right)}}{7} + \frac{8 i \operatorname{im}{\left(y\right)}}{7} - 1$$
x1 = 8*re(y)/7 + 8*i*im(y)/7 - 1
