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:
$$18 x = 8 y - 2$$
Divide both parts of the equation by 18
We get the answer: x = -1/9 + 4*y/9
18*x-8*y = -2
Looking for similar summands in the left part:
-8*y + 18*x = -2
Move the summands with the other variables
from left part to right part, we given:
$$18 x = 8 y - 2$$
Divide both parts of the equation by 18
x = -2 + 8*y / (18)
We get the answer: x = -1/9 + 4*y/9
