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
$$x_{1} = \frac{\operatorname{re}{\left(y\right)}}{7} + \frac{i \operatorname{im}{\left(y\right)}}{7}$$
