How to use it?
- Express {x} in terms of y where:
- 1*x+11*y=-3
- 10*x+3*y=2
- -20*x+14*y=16
- 15*x-3*y=19
- Equation:
-
Equation 25*x^2=16

The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move the summands with the other variables
from left part to right part, we given:
$$- 2 x = 2 y + 4$$
Divide both parts of the equation by -2
We get the answer: x = -2 - y
-2*x-2*y = 4
Looking for similar summands in the left part:
-2*x - 2*y = 4
Move the summands with the other variables
from left part to right part, we given:
$$- 2 x = 2 y + 4$$
Divide both parts of the equation by -2
x = 4 + 2*y / (-2)
We get the answer: x = -2 - y

x1 = -2 - re(y) - I*im(y)
$$x_{1} = - \operatorname{re}{\left(y\right)} - i \operatorname{im}{\left(y\right)} - 2$$
x1 = -re(y) - i*im(y) - 2
