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