How to use it?
- Express {x} in terms of y where:
- -2*x+4*y=3
- 3*x-17*y=-6
- -5*x-9*y=-18
- -17*x+14*y=11
- Equation:
-
Equation (x+7)*(x-1)=0
-
Equation sin(x)=0
- Equation x^3-25*x=0
-
Equation 5x-1=15+x
- Sum of series:
-
-18
-
Identical expressions
- - five *x- nine *y=- eighteen
- minus 5 multiply by x minus 9 multiply by y equally minus 18
- minus five multiply by x minus nine multiply by y equally minus eighteen
- -5x-9y=-18

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:
$$- 5 x = 9 y - 18$$
Divide both parts of the equation by -5
We get the answer: x = 18/5 - 9*y/5
-5*x-9*y = -18
Looking for similar summands in the left part:
-9*y - 5*x = -18
Move the summands with the other variables
from left part to right part, we given:
$$- 5 x = 9 y - 18$$
Divide both parts of the equation by -5
x = -18 + 9*y / (-5)
We get the answer: x = 18/5 - 9*y/5

$$x_{1} = - \frac{9 \operatorname{re}{\left(y\right)}}{5} - \frac{9 i \operatorname{im}{\left(y\right)}}{5} + \frac{18}{5}$$
x1 = -9*re(y)/5 - 9*i*im(y)/5 + 18/5
