How to use it?
- Express {x} in terms of y where:
- -6*x-17*y=14
- 4*x-18*y=-14
- -14*x-1*y=3
- 1*x-6*y=-19
- Equation:
-
Equation x^2=11
-
Equation 2*x^2+6*x+9=0
-
Equation 10(x-9)=7
-
Equation (x+2)^4+(x+2)^2-12=0
-
Identical expressions
- four *x- eighteen *y=- fourteen
- 4 multiply by x minus 18 multiply by y equally minus 14
- four multiply by x minus eighteen multiply by y equally minus fourteen
- 4x-18y=-14
-
Similar expressions
- 4*x-18*y=+14
- 4*x+18*y=-14

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:
$$4 x = 18 y - 14$$
Divide both parts of the equation by 4
We get the answer: x = -7/2 + 9*y/2
4*x-18*y = -14
Looking for similar summands in the left part:
-18*y + 4*x = -14
Move the summands with the other variables
from left part to right part, we given:
$$4 x = 18 y - 14$$
Divide both parts of the equation by 4
x = -14 + 18*y / (4)
We get the answer: x = -7/2 + 9*y/2

$$x_{1} = \frac{9 \operatorname{re}{\left(y\right)}}{2} + \frac{9 i \operatorname{im}{\left(y\right)}}{2} - \frac{7}{2}$$
x1 = 9*re(y)/2 + 9*i*im(y)/2 - 7/2
