How to use it?
- Express {x} in terms of y where:
- 7*x-2*y=18
- 18*x+19*y=7
- 8*x-13*y=-12
- -10*x+13*y=5
- Equation:
-
Equation 2*x^2+5*x-12=0
-
Equation x^2+2x-8=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:
$$- 15 x = 19 y + 2$$
Divide both parts of the equation by -15
We get the answer: x = -2/15 - 19*y/15
-15*x-19*y = 2
Looking for similar summands in the left part:
-19*y - 15*x = 2
Move the summands with the other variables
from left part to right part, we given:
$$- 15 x = 19 y + 2$$
Divide both parts of the equation by -15
x = 2 + 19*y / (-15)
We get the answer: x = -2/15 - 19*y/15

x1 = - -- - -------- - ----------
15 15 15
$$x_{1} = - \frac{19 \operatorname{re}{\left(y\right)}}{15} - \frac{19 i \operatorname{im}{\left(y\right)}}{15} - \frac{2}{15}$$
x1 = -19*re(y)/15 - 19*i*im(y)/15 - 2/15
