How to use it?
- Express {x} in terms of y where:
- 17*x+20*y=-12
- -11*x+10*y=-9
- 12*x-13*y=-14
- 12*x-14*y=20
- Equation:
-
Equation 1-5*x=-6*x+8
- Equation x+y+2=0
-
Equation (5x+2)(-x-4)=0
-
Equation -x/12+x=55/12
-
Identical expressions
- nine *x+ nine *y=- twenty
- 9 multiply by x plus 9 multiply by y equally minus 20
- nine multiply by x plus nine multiply by y equally minus twenty
- 9x+9y=-20
-
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:
$$9 x = - 9 y - 20$$
Divide both parts of the equation by 9
We get the answer: x = -20/9 - y
9*x+9*y = -20
Looking for similar summands in the left part:
9*x + 9*y = -20
Move the summands with the other variables
from left part to right part, we given:
$$9 x = - 9 y - 20$$
Divide both parts of the equation by 9
x = -20 - 9*y / (9)
We get the answer: x = -20/9 - y

x1 = -20/9 - re(y) - I*im(y)
$$x_{1} = - \operatorname{re}{\left(y\right)} - i \operatorname{im}{\left(y\right)} - \frac{20}{9}$$
x1 = -re(y) - i*im(y) - 20/9
