How to use it?
- Express {x} in terms of y where:
- 4*x+2*y=5
- 1*x+10*y=-18
- 13*x-15*y=-6
- -10*x-18*y=15
- Equation:
- Equation x-y=1
-
Equation 4-6(x+2)=3-5x
-
Equation 1/(x-3)^2-3/(x-3)-4=0
-
Equation 14/(x-3)=-7/9
-
Identical expressions
- two *x- eight *y= four
- 2 multiply by x minus 8 multiply by y equally 4
- two multiply by x minus eight multiply by y equally four
- 2x-8y=4

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:
$$2 x = 8 y + 4$$
Divide both parts of the equation by 2
We get the answer: x = 2 + 4*y
2*x-8*y = 4
Looking for similar summands in the left part:
-8*y + 2*x = 4
Move the summands with the other variables
from left part to right part, we given:
$$2 x = 8 y + 4$$
Divide both parts of the equation by 2
x = 4 + 8*y / (2)
We get the answer: x = 2 + 4*y

x1 = 2 + 4*re(y) + 4*I*im(y)
$$x_{1} = 4 \operatorname{re}{\left(y\right)} + 4 i \operatorname{im}{\left(y\right)} + 2$$
x1 = 4*re(y) + 4*i*im(y) + 2
