Express x in terms of y where -12*x-3*y=-9
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
-12*x-3*y = -9
Looking for similar summands in the left part:
-12*x - 3*y = -9
Move the summands with the other variables
from left part to right part, we given:
$$- 12 x = 3 y - 9$$
Divide both parts of the equation by -12
x = -9 + 3*y / (-12)
We get the answer: x = 3/4 - y/4
3 re(y) I*im(y)
x1 = - - ----- - -------
4 4 4
$$x_{1} = - \frac{\operatorname{re}{\left(y\right)}}{4} - \frac{i \operatorname{im}{\left(y\right)}}{4} + \frac{3}{4}$$
x1 = -re(y)/4 - i*im(y)/4 + 3/4
