How to use it?
- Express {x} in terms of y where:
- -16*x-20*y=-13
- 4*x+5*y=7
- -5*x+7*y=-18
- -11*x-20*y=9
- Equation:
- Equation x+y=15
-
Equation -(-y+4)+2*y+1=0
-
Equation 11-5(2x+1)=41-9x
- Equation 2*x^2+50=0
-
Identical expressions
- twelve *x- thirteen *y= two
- 12 multiply by x minus 13 multiply by y equally 2
- twelve multiply by x minus thirteen multiply by y equally two

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:
$$12 x = 13 y + 2$$
Divide both parts of the equation by 12
We get the answer: x = 1/6 + 13*y/12
12*x-13*y = 2
Looking for similar summands in the left part:
-13*y + 12*x = 2
Move the summands with the other variables
from left part to right part, we given:
$$12 x = 13 y + 2$$
Divide both parts of the equation by 12
x = 2 + 13*y / (12)
We get the answer: x = 1/6 + 13*y/12

$$x_{1} = \frac{13 \operatorname{re}{\left(y\right)}}{12} + \frac{13 i \operatorname{im}{\left(y\right)}}{12} + \frac{1}{6}$$
x1 = 13*re(y)/12 + 13*i*im(y)/12 + 1/6
