How to use it?
- Express {x} in terms of y where:
- -14*x-8*y=20
- -2*x-19*y=3
- 8*x+6*y=20
- -11*x-19*y=14
- Equation:
- Equation x+y=5
-
Equation x^2+5x+6=0
-

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:
$$15 x = - 12 y - 19$$
Divide both parts of the equation by 15
We get the answer: x = -19/15 - 4*y/5
15*x+12*y = -19
Looking for similar summands in the left part:
12*y + 15*x = -19
Move the summands with the other variables
from left part to right part, we given:
$$15 x = - 12 y - 19$$
Divide both parts of the equation by 15
x = -19 - 12*y / (15)
We get the answer: x = -19/15 - 4*y/5

$$x_{1} = - \frac{4 \operatorname{re}{\left(y\right)}}{5} - \frac{4 i \operatorname{im}{\left(y\right)}}{5} - \frac{19}{15}$$
x1 = -4*re(y)/5 - 4*i*im(y)/5 - 19/15
