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:
$$9 x = 14 - 2 y$$
Divide both parts of the equation by 9
We get the answer: x = 14/9 - 2*y/9
9*x+2*y = 14
Looking for similar summands in the left part:
2*y + 9*x = 14
Move the summands with the other variables
from left part to right part, we given:
$$9 x = 14 - 2 y$$
Divide both parts of the equation by 9
x = 14 - 2*y / (9)
We get the answer: x = 14/9 - 2*y/9
