How to use it?
- Express {x} in terms of y where:
- -17*x+1*y=-11
- 1*x+4*y=20
- -18*x-2*y=9
- -20*x-14*y=5
- Equation:
-
Equation 14/(x-3)=-7/9
-
Equation x^2-3*x+1=0
-
Equation 13x+10=6x-4
-
Equation x^4+2*x^2-8=0
-
Identical expressions
- - nine *x- one *y= six
- minus 9 multiply by x minus 1 multiply by y equally 6
- minus nine multiply by x minus one multiply by y equally six
- -9x-1y=6
-
Similar expressions

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:
$$- 9 x = y + 6$$
Divide both parts of the equation by -9
We get the answer: x = -2/3 - y/9
-9*x-1*y = 6
Looking for similar summands in the left part:
-y - 9*x = 6
Move the summands with the other variables
from left part to right part, we given:
$$- 9 x = y + 6$$
Divide both parts of the equation by -9
x = 6 + y / (-9)
We get the answer: x = -2/3 - y/9

$$x_{1} = - \frac{\operatorname{re}{\left(y\right)}}{9} - \frac{i \operatorname{im}{\left(y\right)}}{9} - \frac{2}{3}$$
x1 = -re(y)/9 - i*im(y)/9 - 2/3
