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:
$$- 17 x = 16 - 7 y$$
Divide both parts of the equation by -17
We get the answer: x = -16/17 + 7*y/17
-17*x+7*y = 16
Looking for similar summands in the left part:
-17*x + 7*y = 16
Move the summands with the other variables
from left part to right part, we given:
$$- 17 x = 16 - 7 y$$
Divide both parts of the equation by -17
x = 16 - 7*y / (-17)
We get the answer: x = -16/17 + 7*y/17

x1 = - -- + ------- + ---------
17 17 17
$$x_{1} = \frac{7 \operatorname{re}{\left(y\right)}}{17} + \frac{7 i \operatorname{im}{\left(y\right)}}{17} - \frac{16}{17}$$
x1 = 7*re(y)/17 + 7*i*im(y)/17 - 16/17
