Express x in terms of y where 5*x-20*y=-3
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
5*x-20*y = -3
Looking for similar summands in the left part:
-20*y + 5*x = -3
Move the summands with the other variables
from left part to right part, we given:
$$5 x = 20 y - 3$$
Divide both parts of the equation by 5
x = -3 + 20*y / (5)
We get the answer: x = -3/5 + 4*y
x1 = -3/5 + 4*re(y) + 4*I*im(y)
$$x_{1} = 4 \operatorname{re}{\left(y\right)} + 4 i \operatorname{im}{\left(y\right)} - \frac{3}{5}$$
x1 = 4*re(y) + 4*i*im(y) - 3/5
