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
- - thirteen *x+ nine *y= one
- minus 13 multiply by x plus 9 multiply by y equally 1
- minus thirteen multiply by x plus nine multiply by y equally one
- -13x+9y=1
-
Similar expressions
- -13*x-9*y=1
- 13*x+9*y=1

The teacher will be very surprised to see your correct solution 😉
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:
$$- 13 x = 1 - 9 y$$
Divide both parts of the equation by -13
We get the answer: x = -1/13 + 9*y/13
-13*x+9*y = 1
Looking for similar summands in the left part:
-13*x + 9*y = 1
Move the summands with the other variables
from left part to right part, we given:
$$- 13 x = 1 - 9 y$$
Divide both parts of the equation by -13
x = 1 - 9*y / (-13)
We get the answer: x = -1/13 + 9*y/13

1 9*re(y) 9*I*im(y)
x1 = - -- + ------- + ---------
13 13 13
$$x_{1} = \frac{9 \operatorname{re}{\left(y\right)}}{13} + \frac{9 i \operatorname{im}{\left(y\right)}}{13} - \frac{1}{13}$$
x1 = 9*re(y)/13 + 9*i*im(y)/13 - 1/13
