Express x in terms of y where 10*x-2*y=18
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
10*x-2*y = 18
Looking for similar summands in the left part:
-2*y + 10*x = 18
Move the summands with the other variables
from left part to right part, we given:
$$10 x = 2 y + 18$$
Divide both parts of the equation by 10
x = 18 + 2*y / (10)
We get the answer: x = 9/5 + y/5
9 re(y) I*im(y)
x1 = - + ----- + -------
5 5 5
$$x_{1} = \frac{\operatorname{re}{\left(y\right)}}{5} + \frac{i \operatorname{im}{\left(y\right)}}{5} + \frac{9}{5}$$
x1 = re(y)/5 + i*im(y)/5 + 9/5
