Express x in terms of y where 2*x+20*y=-7
The teacher will be very surprised to see your correct solution 😉
The solution
Detail solution
Given the linear equation:
2*x+20*y = -7
Looking for similar summands in the left part:
2*x + 20*y = -7
Move the summands with the other variables
from left part to right part, we given:
$$2 x = - 20 y - 7$$
Divide both parts of the equation by 2
x = -7 - 20*y / (2)
We get the answer: x = -7/2 - 10*y
x1 = -7/2 - 10*re(y) - 10*I*im(y)
$$x_{1} = - 10 \operatorname{re}{\left(y\right)} - 10 i \operatorname{im}{\left(y\right)} - \frac{7}{2}$$
x1 = -10*re(y) - 10*i*im(y) - 7/2
