Express x in terms of y where 7*x+1*y=0
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
7*x+1*y = 0
Looking for similar summands in the left part:
y + 7*x = 0
Move the summands with the other variables
from left part to right part, we given:
$$7 x = - y$$
Divide both parts of the equation by 7
x = -y / (7)
We get the answer: x = -y/7
re(y) I*im(y)
x1 = - ----- - -------
7 7
$$x_{1} = - \frac{\operatorname{re}{\left(y\right)}}{7} - \frac{i \operatorname{im}{\left(y\right)}}{7}$$
x1 = -re(y)/7 - i*im(y)/7
