Express x in terms of y where 3*x-20*y=-9
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
3*x-20*y = -9
Looking for similar summands in the left part:
-20*y + 3*x = -9
Move the summands with the other variables
from left part to right part, we given:
$$3 x = 20 y - 9$$
Divide both parts of the equation by 3
x = -9 + 20*y / (3)
We get the answer: x = -3 + 20*y/3
20*re(y) 20*I*im(y)
x1 = -3 + -------- + ----------
3 3
$$x_{1} = \frac{20 \operatorname{re}{\left(y\right)}}{3} + \frac{20 i \operatorname{im}{\left(y\right)}}{3} - 3$$
x1 = 20*re(y)/3 + 20*i*im(y)/3 - 3
