How to use it?
- Express {x} in terms of y where:
- -10*x+16*y=-6
- -13*x+9*y=1
- -10*x+9*y=-6
- -17*x+13*y=-3
- Equation:
-
Equation (x-3)*(x+4)=0
-
Equation x^3-x^2-5=0
-
Equation x-2(3x+2)=16
- Equation x^2-1=1+(1/2)*y
-
Identical expressions
- - seven *x+ seven *y=- fourteen
- minus 7 multiply by x plus 7 multiply by y equally minus 14
- minus seven multiply by x plus seven multiply by y equally minus fourteen
- -7x+7y=-14
-
Similar expressions
- -7*x+7*y=+14

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:
$$- 7 x = - 7 y - 14$$
Divide both parts of the equation by -7
We get the answer: x = 2 + y
-7*x+7*y = -14
Looking for similar summands in the left part:
-7*x + 7*y = -14
Move the summands with the other variables
from left part to right part, we given:
$$- 7 x = - 7 y - 14$$
Divide both parts of the equation by -7
x = -14 - 7*y / (-7)
We get the answer: x = 2 + y

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