How to use it?
- Express {x} in terms of y where:
- -1*x+1*y=-13
- 9*x-1*y=-10
- -19*x+20*y=-11
- -10*x+4*y=-7
- Equation:
-
Equation (x-4)/x=(2*x+10)/(x+4)
-
Equation x^2+11*x+30=0
-
Equation 9*x^2-1=0
-
Equation 2*sin(x)*cos(x)=0
-
Identical expressions
- - fourteen *x+ six *y= seven
- minus 14 multiply by x plus 6 multiply by y equally 7
- minus fourteen multiply by x plus six multiply by y equally seven
- -14x+6y=7
-
Similar expressions

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:
$$- 14 x = 7 - 6 y$$
Divide both parts of the equation by -14
We get the answer: x = -1/2 + 3*y/7
-14*x+6*y = 7
Looking for similar summands in the left part:
-14*x + 6*y = 7
Move the summands with the other variables
from left part to right part, we given:
$$- 14 x = 7 - 6 y$$
Divide both parts of the equation by -14
x = 7 - 6*y / (-14)
We get the answer: x = -1/2 + 3*y/7

$$x_{1} = \frac{3 \operatorname{re}{\left(y\right)}}{7} + \frac{3 i \operatorname{im}{\left(y\right)}}{7} - \frac{1}{2}$$
x1 = 3*re(y)/7 + 3*i*im(y)/7 - 1/2
