How to use it?
- Express {x} in terms of y where:
- 18*x-10*y=-9
- 18*x-12*y=-9
- 12*x+11*y=20
- 19*x-12*y=-9
- Equation:
-
Equation 7*x=0
-
Equation 3x-2=x+4
-
Equation tan(x)=7
-
Equation (x-3)(x^2-2x+1)=3(x-1)
-
Identical expressions
- one *x- twenty *y= one
- 1 multiply by x minus 20 multiply by y equally 1
- one multiply by x minus twenty multiply by y equally one
- 1x-20y=1
-
Similar expressions
- 1*x+20*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:
$$x = 20 y + 1$$
We get the answer: x = 1 + 20*y
1*x-20*y = 1
Looking for similar summands in the left part:
x - 20*y = 1
Move the summands with the other variables
from left part to right part, we given:
$$x = 20 y + 1$$
We get the answer: x = 1 + 20*y

x1 = 1 + 20*re(y) + 20*I*im(y)
$$x_{1} = 20 \operatorname{re}{\left(y\right)} + 20 i \operatorname{im}{\left(y\right)} + 1$$
x1 = 20*re(y) + 20*i*im(y) + 1
