- -6*x+2*y=-10
- -3*x-6*y=18
- 10*x-18*y=6
- Equation:
-
Equation 2+3x=-2x-13
-
Equation cos(x)=-(1/2)
-
Equation |x^2-1|-|x-3|=7
-
Equation -x-2+3*(x-3)=3*(4-x)-3

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:
$$10 x = 18 y + 6$$
Divide both parts of the equation by 10
We get the answer: x = 3/5 + 9*y/5
10*x-18*y = 6
Looking for similar summands in the left part:
-18*y + 10*x = 6
Move the summands with the other variables
from left part to right part, we given:
$$10 x = 18 y + 6$$
Divide both parts of the equation by 10
x = 6 + 18*y / (10)
We get the answer: x = 3/5 + 9*y/5

$$x_{1} = \frac{9 \operatorname{re}{\left(y\right)}}{5} + \frac{9 i \operatorname{im}{\left(y\right)}}{5} + \frac{3}{5}$$
x1 = 9*re(y)/5 + 9*i*im(y)/5 + 3/5
