How to use it?
- Express {x} in terms of y where:
- -17*x+14*y=11
- -1*x-17*y=10
- 3*x+3*y=10
- 12*x+12*y=-3
- Equation:
-
Equation x^2+2x+1=0
-
Equation cos(x/2)=1/2
-
Equation (x+7)*(x-1)=0
-
Equation -4/7*x^2+28=0
-
Identical expressions
- - six *x- two *y= seven
- minus 6 multiply by x minus 2 multiply by y equally 7
- minus six multiply by x minus two multiply by y equally seven
- -6x-2y=7
-
Similar expressions
- 6*x-2*y=7
- -6*x+2*y=7

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

$$x_{1} = - \frac{\operatorname{re}{\left(y\right)}}{3} - \frac{i \operatorname{im}{\left(y\right)}}{3} - \frac{7}{6}$$
x1 = -re(y)/3 - i*im(y)/3 - 7/6
