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:
$$2 x = 14 - 3 y$$
Divide both parts of the equation by 2
We get the answer: x = 7 - 3*y/2
2*x+3*y = 14
Looking for similar summands in the left part:
2*x + 3*y = 14
Move the summands with the other variables
from left part to right part, we given:
$$2 x = 14 - 3 y$$
Divide both parts of the equation by 2
x = 14 - 3*y / (2)
We get the answer: x = 7 - 3*y/2

$$x_{1} = - \frac{3 \operatorname{re}{\left(y\right)}}{2} - \frac{3 i \operatorname{im}{\left(y\right)}}{2} + 7$$
x1 = -3*re(y)/2 - 3*i*im(y)/2 + 7
