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:
$$6 x = 20 y + 8$$
Divide both parts of the equation by 6
We get the answer: x = 4/3 + 10*y/3
6*x-20*y = 8
Looking for similar summands in the left part:
-20*y + 6*x = 8
Move the summands with the other variables
from left part to right part, we given:
$$6 x = 20 y + 8$$
Divide both parts of the equation by 6
x = 8 + 20*y / (6)
We get the answer: x = 4/3 + 10*y/3
