How to use it?
- Express {x} in terms of y where:
- 14*x+17*y=19
- 19*x-2*y=-17
- 18*x-6*y=7
- -15*x+3*y=8
- Equation:
-
Equation x^2-11*x+28=0
-
Equation 2/3*x=6
-
Equation (x+9)/7-x/2=2
-
Equation 0*x=3
-
Identical expressions
- eight *x- eleven *y=- twenty
- 8 multiply by x minus 11 multiply by y equally minus 20
- eight multiply by x minus eleven multiply by y equally minus twenty
- 8x-11y=-20
-
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:
$$8 x = 11 y - 20$$
Divide both parts of the equation by 8
We get the answer: x = -5/2 + 11*y/8
8*x-11*y = -20
Looking for similar summands in the left part:
-11*y + 8*x = -20
Move the summands with the other variables
from left part to right part, we given:
$$8 x = 11 y - 20$$
Divide both parts of the equation by 8
x = -20 + 11*y / (8)
We get the answer: x = -5/2 + 11*y/8
