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^4+2*x^2-8=0
-
Equation 9x−9(x+1)=−2x
-
Equation x^4+4=0
-
Identical expressions
- - eighteen *x- two *y= nine
- minus 18 multiply by x minus 2 multiply by y equally 9

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:
$$- 18 x = 2 y + 9$$
Divide both parts of the equation by -18
We get the answer: x = -1/2 - y/9
-18*x-2*y = 9
Looking for similar summands in the left part:
-18*x - 2*y = 9
Move the summands with the other variables
from left part to right part, we given:
$$- 18 x = 2 y + 9$$
Divide both parts of the equation by -18
x = 9 + 2*y / (-18)
We get the answer: x = -1/2 - y/9

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