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:
$$- 16 x = 14 y - 18$$
Divide both parts of the equation by -16
We get the answer: x = 9/8 - 7*y/8
-16*x-14*y = -18
Looking for similar summands in the left part:
-16*x - 14*y = -18
Move the summands with the other variables
from left part to right part, we given:
$$- 16 x = 14 y - 18$$
Divide both parts of the equation by -16
x = -18 + 14*y / (-16)
We get the answer: x = 9/8 - 7*y/8

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