- -7*x-20*y=-5
- 5*x-6*y=3
- -20*x+17*y=-16
- -8*x-2*y=-15
- Equation:
-
Equation sin(x)=cos(x)
-
Equation x^3=3
-
Equation cos(x)=(-1/2)
-
Equation sin(x-1)=0
-
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:
$$- 18 x = 4 - 3 y$$
Divide both parts of the equation by -18
We get the answer: x = -2/9 + y/6
-18*x+3*y = 4
Looking for similar summands in the left part:
-18*x + 3*y = 4
Move the summands with the other variables
from left part to right part, we given:
$$- 18 x = 4 - 3 y$$
Divide both parts of the equation by -18
x = 4 - 3*y / (-18)
We get the answer: x = -2/9 + y/6

$$x_{1} = \frac{\operatorname{re}{\left(y\right)}}{6} + \frac{i \operatorname{im}{\left(y\right)}}{6} - \frac{2}{9}$$
x1 = re(y)/6 + i*im(y)/6 - 2/9
