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