How to use it?
- Express {x} in terms of y where:
- -17*x+14*y=11
- -1*x-17*y=10
- 3*x+3*y=10
- 12*x+12*y=-3
- Equation:
-
Equation x^2+2x+1=0
-
Equation cos(x/2)=1/2
-
Equation (x+7)*(x-1)=0
-
Equation -4/7*x^2+28=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:
$$18 x = 3 y + 4$$
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:
-3*y + 18*x = 4
Move the summands with the other variables
from left part to right part, we given:
$$18 x = 3 y + 4$$
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
