How to use it?
- Express {x} in terms of y where:
- -2*x+4*y=3
- 3*x-17*y=-6
- -5*x-9*y=-18
- -17*x+14*y=11
- Equation:
-
Equation (x+7)*(x-1)=0
-
Equation sin(x)=0
- Equation x^3-25*x=0
-
Equation (x+3)^2=(x-4)^2
-
Identical expressions
- twenty *x+ sixteen *y= three
- 20 multiply by x plus 16 multiply by y equally 3
- twenty multiply by x plus sixteen multiply by y equally three

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:
$$20 x = 3 - 16 y$$
Divide both parts of the equation by 20
We get the answer: x = 3/20 - 4*y/5
20*x+16*y = 3
Looking for similar summands in the left part:
16*y + 20*x = 3
Move the summands with the other variables
from left part to right part, we given:
$$20 x = 3 - 16 y$$
Divide both parts of the equation by 20
x = 3 - 16*y / (20)
We get the answer: x = 3/20 - 4*y/5

$$x_{1} = - \frac{4 \operatorname{re}{\left(y\right)}}{5} - \frac{4 i \operatorname{im}{\left(y\right)}}{5} + \frac{3}{20}$$
x1 = -4*re(y)/5 - 4*i*im(y)/5 + 3/20
