How to use it?
- Express {x} in terms of y where:
- -14*x+4*y=-16
- -13*x-10*y=5
- 9*x-1*y=17
- -12*x-8*y=13
- Equation:
-
Equation x^2+4*x+4=0
-
Equation (x^2-4)^2+(x^2-3x-10)^2=0
-
Equation -x/3+x+7=3
-
Equation -20*(x-13)=-220

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

$$x_{1} = \frac{3 \operatorname{re}{\left(y\right)}}{5} + \frac{3 i \operatorname{im}{\left(y\right)}}{5} + \frac{9}{10}$$
x1 = 3*re(y)/5 + 3*i*im(y)/5 + 9/10
