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:
$$- 9 x = 16 y - 7$$
Divide both parts of the equation by -9
We get the answer: x = 7/9 - 16*y/9
-9*x-16*y = -7
Looking for similar summands in the left part:
-16*y - 9*x = -7
Move the summands with the other variables
from left part to right part, we given:
$$- 9 x = 16 y - 7$$
Divide both parts of the equation by -9
x = -7 + 16*y / (-9)
We get the answer: x = 7/9 - 16*y/9

$$x_{1} = - \frac{16 \operatorname{re}{\left(y\right)}}{9} - \frac{16 i \operatorname{im}{\left(y\right)}}{9} + \frac{7}{9}$$
x1 = -16*re(y)/9 - 16*i*im(y)/9 + 7/9
