How to use it?
- Express {x} in terms of y where:
- -18*x-1*y=-11
- 7*x-2*y=20
- -1*x-20*y=-17
- -2*x-14*y=7
- Equation:
-
Equation 2x=18-x
-
Equation x^4=(2*x-3)^2
-
Equation 9*x^2=54*x
-
Equation cos(x)+sin(x)=0
-
Identical expressions
- - one *x- twenty *y=- seventeen
- minus 1 multiply by x minus 20 multiply by y equally minus 17
- minus one multiply by x minus twenty multiply by y equally minus seventeen
- -1x-20y=-17
-
Similar expressions
- -1*x-20*y=+17
- -1*x+20*y=-17

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:
$$- x = 20 y - 17$$
Divide both parts of the equation by -1
We get the answer: x = 17 - 20*y
-1*x-20*y = -17
Looking for similar summands in the left part:
-x - 20*y = -17
Move the summands with the other variables
from left part to right part, we given:
$$- x = 20 y - 17$$
Divide both parts of the equation by -1
x = -17 + 20*y / (-1)
We get the answer: x = 17 - 20*y

x1 = 17 - 20*re(y) - 20*I*im(y)
$$x_{1} = - 20 \operatorname{re}{\left(y\right)} - 20 i \operatorname{im}{\left(y\right)} + 17$$
x1 = -20*re(y) - 20*i*im(y) + 17
