How to use it?
- Express {x} in terms of y where:
- 7*x+13*y=-13
- 7*x+19*y=12
- 1*x+20*y=-17
- 14*x-16*y=-3
- Equation:
-
Equation (x+2)^2=(1-x)^2
-
Equation 2*cos(x)+1=0
-
Equation (-5*x-3)*(2*x-1)=0

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:
$$x = - 20 y - 17$$
We get the answer: x = -17 - 20*y
1*x+20*y = -17
Looking for similar summands in the left part:
x + 20*y = -17
Move the summands with the other variables
from left part to right part, we given:
$$x = - 20 y - 17$$
We get the answer: x = -17 - 20*y

x1 = -17 - 20*re(y) - 20*I*im(y)
$$x_{1} = - 20 \operatorname{re}{\left(y\right)} - 20 i \operatorname{im}{\left(y\right)} - 17$$
x1 = -20*re(y) - 20*i*im(y) - 17
