Express x in terms of y where 9*x-15*y=-4
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
9*x-15*y = -4
Looking for similar summands in the left part:
-15*y + 9*x = -4
Move the summands with the other variables
from left part to right part, we given:
$$9 x = 15 y - 4$$
Divide both parts of the equation by 9
x = -4 + 15*y / (9)
We get the answer: x = -4/9 + 5*y/3
4 5*re(y) 5*I*im(y)
x1 = - - + ------- + ---------
9 3 3
$$x_{1} = \frac{5 \operatorname{re}{\left(y\right)}}{3} + \frac{5 i \operatorname{im}{\left(y\right)}}{3} - \frac{4}{9}$$
x1 = 5*re(y)/3 + 5*i*im(y)/3 - 4/9
