How to use it?
- Express {x} in terms of y where:
- -16*x+7*y=-5
- -2*x-1*y=-8
- -4*x-18*y=-14
- 1*x-4*y=1
- Equation:
-
Equation sin(x)=1
-
Equation (7x+1)-(9x+3)=5
-
Equation sin(x^2)=0
-
Equation (x+2)^2+(x-3)^2=2x^2
-
Identical expressions
- - four *x- eighteen *y=- fourteen
- minus 4 multiply by x minus 18 multiply by y equally minus 14
- minus 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
- -4*x+18*y=-14
Express x in terms of y where -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
