How to use it?
- Express {x} in terms of y where:
- -10*x-18*y=15
- 2*x-15*y=-1
- -19*x-5*y=-16
- 13*x+7*y=11
- Equation:
-
Equation -x/12+x=55/12
-
Equation 9/(x-2)=9/2
-
Equation 2-3*(2*x+2)=5-4*x
-
Equation -4x=15-3(3x-5)
- 9*x+4*y
-
Identical 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:
$$9 x = 2 - 4 y$$
Divide both parts of the equation by 9
We get the answer: x = 2/9 - 4*y/9
9*x+4*y = 2
Looking for similar summands in the left part:
4*y + 9*x = 2
Move the summands with the other variables
from left part to right part, we given:
$$9 x = 2 - 4 y$$
Divide both parts of the equation by 9
x = 2 - 4*y / (9)
We get the answer: x = 2/9 - 4*y/9

$$x_{1} = - \frac{4 \operatorname{re}{\left(y\right)}}{9} - \frac{4 i \operatorname{im}{\left(y\right)}}{9} + \frac{2}{9}$$
x1 = -4*re(y)/9 - 4*i*im(y)/9 + 2/9
