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:
$$7 x = 11 - 18 y$$
Divide both parts of the equation by 7
We get the answer: x = 11/7 - 18*y/7
7*x+18*y = 11
Looking for similar summands in the left part:
7*x + 18*y = 11
Move the summands with the other variables
from left part to right part, we given:
$$7 x = 11 - 18 y$$
Divide both parts of the equation by 7
x = 11 - 18*y / (7)
We get the answer: x = 11/7 - 18*y/7

$$x_{1} = - \frac{18 \operatorname{re}{\left(y\right)}}{7} - \frac{18 i \operatorname{im}{\left(y\right)}}{7} + \frac{11}{7}$$
x1 = -18*re(y)/7 - 18*i*im(y)/7 + 11/7
