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:
$$6 x = 9 - 11 y$$
Divide both parts of the equation by 6
We get the answer: x = 3/2 - 11*y/6
6*x+11*y = 9
Looking for similar summands in the left part:
6*x + 11*y = 9
Move the summands with the other variables
from left part to right part, we given:
$$6 x = 9 - 11 y$$
Divide both parts of the equation by 6
x = 9 - 11*y / (6)
We get the answer: x = 3/2 - 11*y/6
