Express x in terms of y where -10*x-9*y=-4
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
-10*x-9*y = -4
Looking for similar summands in the left part:
-10*x - 9*y = -4
Move the summands with the other variables
from left part to right part, we given:
$$- 10 x = 9 y - 4$$
Divide both parts of the equation by -10
x = -4 + 9*y / (-10)
We get the answer: x = 2/5 - 9*y/10
2 9*re(y) 9*I*im(y)
x1 = - - ------- - ---------
5 10 10
$$x_{1} = - \frac{9 \operatorname{re}{\left(y\right)}}{10} - \frac{9 i \operatorname{im}{\left(y\right)}}{10} + \frac{2}{5}$$
x1 = -9*re(y)/10 - 9*i*im(y)/10 + 2/5
