How to use it?
- Express {x} in terms of y where:
- -7*x-7*y=-14
- 10*x-2*y=0
- -15*x+17*y=13
- 2*x+3*y=14
- Equation:
-
Equation (x-2)^2=(x-9)^2
-
Equation 3*9^(x-1/2)-7*6^x+3*4^(x+1)=0
-
Equation √(x^2-1)^3=2*x
-
Equation x+19=12

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:
$$10 x = 2 y$$
Divide both parts of the equation by 10
We get the answer: x = y/5
10*x-2*y = 0
Looking for similar summands in the left part:
-2*y + 10*x = 0
Move the summands with the other variables
from left part to right part, we given:
$$10 x = 2 y$$
Divide both parts of the equation by 10
x = 2*y / (10)
We get the answer: x = y/5

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