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
