How to use it?
- Express {x} in terms of y where:
- -9*x+12*y=16
- -10*x+8*y=2
- 13*x+3*y=6
- 7*x-18*y=-4
- Equation:
-
Equation (x+3)^2=4
-
Equation 2*x^2-18=0
-
Equation 3*x-7/8-x-3/6=1
- Equation (-5*x+3)*(-x+8)=0
-
Identical expressions
- - eight *x+ twelve *y= zero
- minus 8 multiply by x plus 12 multiply by y equally 0
- minus eight multiply by x plus twelve multiply by y equally zero
- -8x+12y=0

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:
$$- 8 x = - 12 y$$
Divide both parts of the equation by -8
We get the answer: x = 3*y/2
-8*x+12*y = 0
Looking for similar summands in the left part:
-8*x + 12*y = 0
Move the summands with the other variables
from left part to right part, we given:
$$- 8 x = - 12 y$$
Divide both parts of the equation by -8
x = -12*y / (-8)
We get the answer: x = 3*y/2

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