The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
19*x+15*y = 15
Looking for similar summands in the left part:
15*y + 19*x = 15
Move the summands with the other variables
from left part to right part, we given:
$$19 x = 15 - 15 y$$
Divide both parts of the equation by 19
x = 15 - 15*y / (19)
We get the answer: x = 15/19 - 15*y/19
15 15*re(y) 15*I*im(y)
x1 = -- - -------- - ----------
19 19 19
$$x_{1} = - \frac{15 \operatorname{re}{\left(y\right)}}{19} - \frac{15 i \operatorname{im}{\left(y\right)}}{19} + \frac{15}{19}$$
x1 = -15*re(y)/19 - 15*i*im(y)/19 + 15/19
