How to use it?
- Express {x} in terms of y where:
- -17*x-15*y=-17
- -2*x+7*y=-14
- -1*x+6*y=-20
- -11*x+10*y=-3
- Equation:
-
Equation x^2+3x=0
-
Equation x-6/2-x/3=3
- Equation (x+20)*(-x+10)=0
-
Equation 0,2x+2,7=1,4-1,1x
-
Identical expressions
- - one *x+ six *y=- twenty
- minus 1 multiply by x plus 6 multiply by y equally minus 20
- minus one multiply by x plus six multiply by y equally minus twenty
- -1x+6y=-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:
$$- x = - 6 y - 20$$
Divide both parts of the equation by -1
We get the answer: x = 20 + 6*y
-1*x+6*y = -20
Looking for similar summands in the left part:
-x + 6*y = -20
Move the summands with the other variables
from left part to right part, we given:
$$- x = - 6 y - 20$$
Divide both parts of the equation by -1
x = -20 - 6*y / (-1)
We get the answer: x = 20 + 6*y

x1 = 20 + 6*re(y) + 6*I*im(y)
$$x_{1} = 6 \operatorname{re}{\left(y\right)} + 6 i \operatorname{im}{\left(y\right)} + 20$$
x1 = 6*re(y) + 6*i*im(y) + 20
