Express x in terms of y where 3*x+19*y=4
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
3*x+19*y = 4
Looking for similar summands in the left part:
3*x + 19*y = 4
Move the summands with the other variables
from left part to right part, we given:
$$3 x = 4 - 19 y$$
Divide both parts of the equation by 3
x = 4 - 19*y / (3)
We get the answer: x = 4/3 - 19*y/3
4 19*re(y) 19*I*im(y)
x1 = - - -------- - ----------
3 3 3
$$x_{1} = - \frac{19 \operatorname{re}{\left(y\right)}}{3} - \frac{19 i \operatorname{im}{\left(y\right)}}{3} + \frac{4}{3}$$
x1 = -19*re(y)/3 - 19*i*im(y)/3 + 4/3
