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:
$$- 9 x = 6 y + 12$$
Divide both parts of the equation by -9
We get the answer: x = -4/3 - 2*y/3
-9*x-6*y = 12
Looking for similar summands in the left part:
-9*x - 6*y = 12
Move the summands with the other variables
from left part to right part, we given:
$$- 9 x = 6 y + 12$$
Divide both parts of the equation by -9
x = 12 + 6*y / (-9)
We get the answer: x = -4/3 - 2*y/3
