Express x in terms of y where 10*x+5*y=10
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
10*x+5*y = 10
Looking for similar summands in the left part:
5*y + 10*x = 10
Move the summands with the other variables
from left part to right part, we given:
$$10 x = 10 - 5 y$$
Divide both parts of the equation by 10
x = 10 - 5*y / (10)
We get the answer: x = 1 - y/2
re(y) I*im(y)
x1 = 1 - ----- - -------
2 2
$$x_{1} = - \frac{\operatorname{re}{\left(y\right)}}{2} - \frac{i \operatorname{im}{\left(y\right)}}{2} + 1$$
x1 = -re(y)/2 - i*im(y)/2 + 1
