How to use it?
- Express {x} in terms of y where:
- -6*x-20*y=8
- -9*x-15*y=-4
- 12*x-14*y=20
- 17*x-20*y=6
- Equation:
-
Equation (x+6)^3=25*(x+6)
-
Equation 1-5x=-6x+8
-
Equation 1-5*x=-6*x+8
-
Equation x^2-8*x+17=0
-
Identical expressions
- - six *x- twenty *y= eight
- minus 6 multiply by x minus 20 multiply by y equally 8
- minus six multiply by x minus twenty multiply by y equally eight
- -6x-20y=8
-
Similar expressions

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:
$$- 6 x = 20 y + 8$$
Divide both parts of the equation by -6
We get the answer: x = -4/3 - 10*y/3
-6*x-20*y = 8
Looking for similar summands in the left part:
-20*y - 6*x = 8
Move the summands with the other variables
from left part to right part, we given:
$$- 6 x = 20 y + 8$$
Divide both parts of the equation by -6
x = 8 + 20*y / (-6)
We get the answer: x = -4/3 - 10*y/3
