How to use it?
- Express {x} in terms of y where:
- -10*x+16*y=-6
- -13*x+9*y=1
- -10*x+9*y=-6
- 9*x-4*y=2
- Equation:
-
Equation x^3-x^2-5=0
-
Equation (-5*x-3)*(2*x-1)=0
- Equation x^2-1=1+(1/2)*y
-

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:
$$9 x = 4 y + 2$$
Divide both parts of the equation by 9
We get the answer: x = 2/9 + 4*y/9
9*x-4*y = 2
Looking for similar summands in the left part:
-4*y + 9*x = 2
Move the summands with the other variables
from left part to right part, we given:
$$9 x = 4 y + 2$$
Divide both parts of the equation by 9
x = 2 + 4*y / (9)
We get the answer: x = 2/9 + 4*y/9

$$x_{1} = \frac{4 \operatorname{re}{\left(y\right)}}{9} + \frac{4 i \operatorname{im}{\left(y\right)}}{9} + \frac{2}{9}$$
x1 = 4*re(y)/9 + 4*i*im(y)/9 + 2/9
