Express x in terms of y where -2*x-7*y=19
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
-2*x-7*y = 19
Looking for similar summands in the left part:
-7*y - 2*x = 19
Move the summands with the other variables
from left part to right part, we given:
$$- 2 x = 7 y + 19$$
Divide both parts of the equation by -2
x = 19 + 7*y / (-2)
We get the answer: x = -19/2 - 7*y/2
19 7*re(y) 7*I*im(y)
x1 = - -- - ------- - ---------
2 2 2
$$x_{1} = - \frac{7 \operatorname{re}{\left(y\right)}}{2} - \frac{7 i \operatorname{im}{\left(y\right)}}{2} - \frac{19}{2}$$
x1 = -7*re(y)/2 - 7*i*im(y)/2 - 19/2
