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:
$$18 x = 4 - 12 y$$
Divide both parts of the equation by 18
We get the answer: x = 2/9 - 2*y/3
18*x+12*y = 4
Looking for similar summands in the left part:
12*y + 18*x = 4
Move the summands with the other variables
from left part to right part, we given:
$$18 x = 4 - 12 y$$
Divide both parts of the equation by 18
x = 4 - 12*y / (18)
We get the answer: x = 2/9 - 2*y/3
