Express x in terms of y where -5*x+19*y=18
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
-5*x+19*y = 18
Looking for similar summands in the left part:
-5*x + 19*y = 18
Move the summands with the other variables
from left part to right part, we given:
$$- 5 x = 18 - 19 y$$
Divide both parts of the equation by -5
x = 18 - 19*y / (-5)
We get the answer: x = -18/5 + 19*y/5
18 19*re(y) 19*I*im(y)
x1 = - -- + -------- + ----------
5 5 5
$$x_{1} = \frac{19 \operatorname{re}{\left(y\right)}}{5} + \frac{19 i \operatorname{im}{\left(y\right)}}{5} - \frac{18}{5}$$
x1 = 19*re(y)/5 + 19*i*im(y)/5 - 18/5
