Express x in terms of y where 4*x+13*y=8
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
4*x+13*y = 8
Looking for similar summands in the left part:
4*x + 13*y = 8
Move the summands with the other variables
from left part to right part, we given:
$$4 x = 8 - 13 y$$
Divide both parts of the equation by 4
x = 8 - 13*y / (4)
We get the answer: x = 2 - 13*y/4
13*re(y) 13*I*im(y)
x1 = 2 - -------- - ----------
4 4
$$x_{1} = - \frac{13 \operatorname{re}{\left(y\right)}}{4} - \frac{13 i \operatorname{im}{\left(y\right)}}{4} + 2$$
x1 = -13*re(y)/4 - 13*i*im(y)/4 + 2
