How to use it?
- Express {x} in terms of y where:
- -6*x+11*y=-5
- -3*x-19*y=-9
- -19*x-15*y=15
- 13*x-11*y=16
- Equation:
-
Equation x^3=3
-
Equation 5-x^2=0
- Equation (-5*x+3)*(-x+8)=0
-
Equation x^2+6=5x
-
Identical expressions
- three *x- one *y= five
- 3 multiply by x minus 1 multiply by y equally 5
- three multiply by x minus one multiply by y equally five
- 3x-1y=5

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:
$$3 x = y + 5$$
Divide both parts of the equation by 3
We get the answer: x = 5/3 + y/3
3*x-1*y = 5
Looking for similar summands in the left part:
-y + 3*x = 5
Move the summands with the other variables
from left part to right part, we given:
$$3 x = y + 5$$
Divide both parts of the equation by 3
x = 5 + y / (3)
We get the answer: x = 5/3 + y/3

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