How to use it?
- Express {x} in terms of y where:
- -7*x-7*y=-14
- 10*x-2*y=0
- -15*x+17*y=13
- 2*x+3*y=14
- Equation:
-
Equation (x-2)^2=(x-9)^2
-
Equation 3*9^(x-1/2)-7*6^x+3*4^(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:
$$- 7 x = 7 y - 14$$
Divide both parts of the equation by -7
We get the answer: x = 2 - y
-7*x-7*y = -14
Looking for similar summands in the left part:
-7*x - 7*y = -14
Move the summands with the other variables
from left part to right part, we given:
$$- 7 x = 7 y - 14$$
Divide both parts of the equation by -7
x = -14 + 7*y / (-7)
We get the answer: x = 2 - y
Rapid solution

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
