How to use it?
- Express {x} in terms of y where:
- 7*x-1*y=-7
- 10*x-15*y=16
- -14*x-12*y=5
- 13*x-12*y=19
- Equation:
- Equation x-y=7
-
Equation 1/(x+6)=2
-
Equation (x-4)^2-x^2=0
-
Equation (x-2)/(x-7)=5/8
-
Identical expressions
- seventeen *x+ nineteen *y= one
- 17 multiply by x plus 19 multiply by y equally 1
- seventeen multiply by x plus nineteen multiply by y equally one
- 17x+19y=1
-
Similar expressions
- 17*x-19*y=1

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:
$$17 x = 1 - 19 y$$
Divide both parts of the equation by 17
We get the answer: x = 1/17 - 19*y/17
17*x+19*y = 1
Looking for similar summands in the left part:
17*x + 19*y = 1
Move the summands with the other variables
from left part to right part, we given:
$$17 x = 1 - 19 y$$
Divide both parts of the equation by 17
x = 1 - 19*y / (17)
We get the answer: x = 1/17 - 19*y/17

17 17 17
$$x_{1} = - \frac{19 \operatorname{re}{\left(y\right)}}{17} - \frac{19 i \operatorname{im}{\left(y\right)}}{17} + \frac{1}{17}$$
x1 = -19*re(y)/17 - 19*i*im(y)/17 + 1/17
