Express x in terms of y where -6*x+20*y=8
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
-6*x+20*y = 8
Looking for similar summands in the left part:
-6*x + 20*y = 8
Move the summands with the other variables
from left part to right part, we given:
$$- 6 x = 8 - 20 y$$
Divide both parts of the equation by -6
x = 8 - 20*y / (-6)
We get the answer: x = -4/3 + 10*y/3
4 10*re(y) 10*I*im(y)
x1 = - - + -------- + ----------
3 3 3
$$x_{1} = \frac{10 \operatorname{re}{\left(y\right)}}{3} + \frac{10 i \operatorname{im}{\left(y\right)}}{3} - \frac{4}{3}$$
x1 = 10*re(y)/3 + 10*i*im(y)/3 - 4/3
