How to use it?
- Express {x} in terms of y where:
- 7*x-1*y=-7
- 10*x-15*y=16
- -14*x-12*y=5
- -14*x+10*y=19
- Equation:
- Equation x^2-10*x-24=0
- Equation x-y=7
-
Equation sin(x)=sqrt(2)/2
-
Equation 1/(x-1)^2+2/(x-1)-3=0
-
Identical expressions
- - two *x+ fourteen *y= nine
- minus 2 multiply by x plus 14 multiply by y equally 9
- minus two multiply by x plus fourteen multiply by y equally nine
- -2x+14y=9
-
Similar expressions
- 2*x+14*y=9
- -2*x-14*y=9

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:
$$- 2 x = 9 - 14 y$$
Divide both parts of the equation by -2
We get the answer: x = -9/2 + 7*y
-2*x+14*y = 9
Looking for similar summands in the left part:
-2*x + 14*y = 9
Move the summands with the other variables
from left part to right part, we given:
$$- 2 x = 9 - 14 y$$
Divide both parts of the equation by -2
x = 9 - 14*y / (-2)
We get the answer: x = -9/2 + 7*y

x1 = -9/2 + 7*re(y) + 7*I*im(y)
$$x_{1} = 7 \operatorname{re}{\left(y\right)} + 7 i \operatorname{im}{\left(y\right)} - \frac{9}{2}$$
x1 = 7*re(y) + 7*i*im(y) - 9/2
