How to use it?
- Express {x} in terms of y where:
- 4*x+8*y=7
- -14*x+5*y=3
- 13*x-18*y=-17
- 4*x+18*y=-7
- Equation:
-
Equation x/4+13=x+1
-
Equation 4(x-8)=-5
-
Equation 5(x-2)^2=-6x-44
-
Equation 2^x=5
-
Identical expressions
- - nine *x+ one *y= six
- minus 9 multiply by x plus 1 multiply by y equally 6
- minus nine multiply by x plus one multiply by y equally six
- -9x+1y=6
-
Similar expressions
- -9*x-1*y=6
- 9*x+1*y=6

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:
$$- 9 x = 6 - y$$
Divide both parts of the equation by -9
We get the answer: x = -2/3 + y/9
-9*x+1*y = 6
Looking for similar summands in the left part:
y - 9*x = 6
Move the summands with the other variables
from left part to right part, we given:
$$- 9 x = 6 - y$$
Divide both parts of the equation by -9
x = 6 - y / (-9)
We get the answer: x = -2/3 + y/9

$$x_{1} = \frac{\operatorname{re}{\left(y\right)}}{9} + \frac{i \operatorname{im}{\left(y\right)}}{9} - \frac{2}{3}$$
x1 = re(y)/9 + i*im(y)/9 - 2/3
