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:
$$12 x = - 14 y - 15$$
Divide both parts of the equation by 12
We get the answer: x = -5/4 - 7*y/6
12*x+14*y = -15
Looking for similar summands in the left part:
12*x + 14*y = -15
Move the summands with the other variables
from left part to right part, we given:
$$12 x = - 14 y - 15$$
Divide both parts of the equation by 12
x = -15 - 14*y / (12)
We get the answer: x = -5/4 - 7*y/6

$$x_{1} = - \frac{7 \operatorname{re}{\left(y\right)}}{6} - \frac{7 i \operatorname{im}{\left(y\right)}}{6} - \frac{5}{4}$$
x1 = -7*re(y)/6 - 7*i*im(y)/6 - 5/4
