How to use it?
- Express {x} in terms of y where:
- 7*x-2*y=18
- 6*x-19*y=-18
- -3*x+19*y=16
- -19*x-2*y=-6
- Equation:
-
Equation 18-x^2=14
-
Equation -x/11+x=50/11
- Equation x^4-24*x^2-25=0
-
Equation x+2=0
-
Identical expressions
- - six *x- eleven *y=- twenty
- minus 6 multiply by x minus 11 multiply by y equally minus 20
- minus six multiply by x minus eleven multiply by y equally minus twenty
- -6x-11y=-20
-
Similar expressions
- 6*x-11*y=-20
- -6*x-11*y=+20

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:
$$- 6 x = 11 y - 20$$
Divide both parts of the equation by -6
We get the answer: x = 10/3 - 11*y/6
-6*x-11*y = -20
Looking for similar summands in the left part:
-11*y - 6*x = -20
Move the summands with the other variables
from left part to right part, we given:
$$- 6 x = 11 y - 20$$
Divide both parts of the equation by -6
x = -20 + 11*y / (-6)
We get the answer: x = 10/3 - 11*y/6

$$x_{1} = - \frac{11 \operatorname{re}{\left(y\right)}}{6} - \frac{11 i \operatorname{im}{\left(y\right)}}{6} + \frac{10}{3}$$
x1 = -11*re(y)/6 - 11*i*im(y)/6 + 10/3
