How to use it?
- Express {x} in terms of y where:
- -14*x+4*y=-16
- -13*x-10*y=5
- 9*x-1*y=17
- -12*x-8*y=13
- Equation:
-
Equation x^2+4*x+4=0
-
Equation (x^2-4)^2+(x^2-3x-10)^2=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:
$$- 13 x = 10 y + 5$$
Divide both parts of the equation by -13
We get the answer: x = -5/13 - 10*y/13
-13*x-10*y = 5
Looking for similar summands in the left part:
-13*x - 10*y = 5
Move the summands with the other variables
from left part to right part, we given:
$$- 13 x = 10 y + 5$$
Divide both parts of the equation by -13
x = 5 + 10*y / (-13)
We get the answer: x = -5/13 - 10*y/13

13 13 13
$$x_{1} = - \frac{10 \operatorname{re}{\left(y\right)}}{13} - \frac{10 i \operatorname{im}{\left(y\right)}}{13} - \frac{5}{13}$$
x1 = -10*re(y)/13 - 10*i*im(y)/13 - 5/13
