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:
$$- 16 x = 7 y + 18$$
Divide both parts of the equation by -16
We get the answer: x = -9/8 - 7*y/16
-16*x-7*y = 18
Looking for similar summands in the left part:
-16*x - 7*y = 18
Move the summands with the other variables
from left part to right part, we given:
$$- 16 x = 7 y + 18$$
Divide both parts of the equation by -16
x = 18 + 7*y / (-16)
We get the answer: x = -9/8 - 7*y/16

$$x_{1} = - \frac{7 \operatorname{re}{\left(y\right)}}{16} - \frac{7 i \operatorname{im}{\left(y\right)}}{16} - \frac{9}{8}$$
x1 = -7*re(y)/16 - 7*i*im(y)/16 - 9/8
