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
- 16*x+14*y=-14
- Equation:
-
Equation x^3=3
-
Equation 5-x^2=0
- Equation (-5*x+3)*(-x+8)=0
-
Equation x^2+6=5x
-
Identical expressions
- - fifteen *x- three *y= seven
- minus 15 multiply by x minus 3 multiply by y equally 7

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:
$$- 15 x = 3 y + 7$$
Divide both parts of the equation by -15
We get the answer: x = -7/15 - y/5
-15*x-3*y = 7
Looking for similar summands in the left part:
-15*x - 3*y = 7
Move the summands with the other variables
from left part to right part, we given:
$$- 15 x = 3 y + 7$$
Divide both parts of the equation by -15
x = 7 + 3*y / (-15)
We get the answer: x = -7/15 - y/5

$$x_{1} = - \frac{\operatorname{re}{\left(y\right)}}{5} - \frac{i \operatorname{im}{\left(y\right)}}{5} - \frac{7}{15}$$
x1 = -re(y)/5 - i*im(y)/5 - 7/15
