Express x in terms of y where 13*x+15*y=9
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
13*x+15*y = 9
Looking for similar summands in the left part:
13*x + 15*y = 9
Move the summands with the other variables
from left part to right part, we given:
$$13 x = 9 - 15 y$$
Divide both parts of the equation by 13
x = 9 - 15*y / (13)
We get the answer: x = 9/13 - 15*y/13
9 15*re(y) 15*I*im(y)
x1 = -- - -------- - ----------
13 13 13
$$x_{1} = - \frac{15 \operatorname{re}{\left(y\right)}}{13} - \frac{15 i \operatorname{im}{\left(y\right)}}{13} + \frac{9}{13}$$
x1 = -15*re(y)/13 - 15*i*im(y)/13 + 9/13
