How to use it?
- Express {x} in terms of y where:
- -16*x+10*y=-11
- 10*x-2*y=11
- -18*x-14*y=12
- -9*x+1*y=3
- Equation:
-
Equation 81*x^3+18*x^2+x=0
-
Equation x(x^2+2x+1)=6(x+1)
-
Equation (-x-4)*(3*x+3)=0
- Equation x^2-144=0
-
Identical expressions
- - nine *x+ one *y= three
- minus 9 multiply by x plus 1 multiply by y equally 3
- minus nine multiply by x plus one multiply by y equally three
- -9x+1y=3
-
Similar expressions
- 9*x+1*y=3

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

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