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:
$$- 15 x = - 11 y - 7$$
Divide both parts of the equation by -15
We get the answer: x = 7/15 + 11*y/15
-15*x+11*y = -7
Looking for similar summands in the left part:
-15*x + 11*y = -7
Move the summands with the other variables
from left part to right part, we given:
$$- 15 x = - 11 y - 7$$
Divide both parts of the equation by -15
x = -7 - 11*y / (-15)
We get the answer: x = 7/15 + 11*y/15

7 11*re(y) 11*I*im(y)
x1 = -- + -------- + ----------
15 15 15
$$x_{1} = \frac{11 \operatorname{re}{\left(y\right)}}{15} + \frac{11 i \operatorname{im}{\left(y\right)}}{15} + \frac{7}{15}$$
x1 = 11*re(y)/15 + 11*i*im(y)/15 + 7/15
