Express x in terms of y where 3*x+8*y=13
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
3*x+8*y = 13
Looking for similar summands in the left part:
3*x + 8*y = 13
Move the summands with the other variables
from left part to right part, we given:
$$3 x = 13 - 8 y$$
Divide both parts of the equation by 3
x = 13 - 8*y / (3)
We get the answer: x = 13/3 - 8*y/3
13 8*re(y) 8*I*im(y)
x1 = -- - ------- - ---------
3 3 3
$$x_{1} = - \frac{8 \operatorname{re}{\left(y\right)}}{3} - \frac{8 i \operatorname{im}{\left(y\right)}}{3} + \frac{13}{3}$$
x1 = -8*re(y)/3 - 8*i*im(y)/3 + 13/3
