How to use it?
- Express {x} in terms of y where:
- 14*x+17*y=19
- 19*x-2*y=-17
- 18*x-6*y=7
- -15*x+3*y=8
- Equation:
-
Equation x^2-11*x+28=0
-
Equation 0*x=3
-
Equation 8,4(y-17,9)=4,2
- Equation x^2-x+30=0
-
Identical expressions
- - two *x+ one *y= five
- minus 2 multiply by x plus 1 multiply by y equally 5
- minus two multiply by x plus one multiply by y equally five
- -2x+1y=5
-
Similar expressions
- 2*x+1*y=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:
$$- 2 x = 5 - y$$
Divide both parts of the equation by -2
We get the answer: x = -5/2 + y/2
-2*x+1*y = 5
Looking for similar summands in the left part:
y - 2*x = 5
Move the summands with the other variables
from left part to right part, we given:
$$- 2 x = 5 - y$$
Divide both parts of the equation by -2
x = 5 - y / (-2)
We get the answer: x = -5/2 + y/2

$$x_{1} = \frac{\operatorname{re}{\left(y\right)}}{2} + \frac{i \operatorname{im}{\left(y\right)}}{2} - \frac{5}{2}$$
x1 = re(y)/2 + i*im(y)/2 - 5/2
