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
- Equation 3*x^2-48=0
-
Equation x^2-5*x+7=0
-
Equation x^2-20=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:
$$9 x = 2 - 19 y$$
Divide both parts of the equation by 9
We get the answer: x = 2/9 - 19*y/9
9*x+19*y = 2
Looking for similar summands in the left part:
9*x + 19*y = 2
Move the summands with the other variables
from left part to right part, we given:
$$9 x = 2 - 19 y$$
Divide both parts of the equation by 9
x = 2 - 19*y / (9)
We get the answer: x = 2/9 - 19*y/9

$$x_{1} = - \frac{19 \operatorname{re}{\left(y\right)}}{9} - \frac{19 i \operatorname{im}{\left(y\right)}}{9} + \frac{2}{9}$$
x1 = -19*re(y)/9 - 19*i*im(y)/9 + 2/9
