How to use it?
- Express {x} in terms of y where:
- 18*x-8*y=-2
- -11*x+15*y=7
- 6*x+17*y=3
- 1*x+10*y=-18
- Equation:
-
Equation 4-6*(x+2)=3-5*x
-
Equation 4-6(x+2)=3-5x

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:
$$x = - 10 y - 18$$
We get the answer: x = -18 - 10*y
1*x+10*y = -18
Looking for similar summands in the left part:
x + 10*y = -18
Move the summands with the other variables
from left part to right part, we given:
$$x = - 10 y - 18$$
We get the answer: x = -18 - 10*y

x1 = -18 - 10*re(y) - 10*I*im(y)
$$x_{1} = - 10 \operatorname{re}{\left(y\right)} - 10 i \operatorname{im}{\left(y\right)} - 18$$
x1 = -10*re(y) - 10*i*im(y) - 18
