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:
$$- 2 y = - 6 x$$
Divide both parts of the equation by -2
We get the answer: y = 3*x
6*x-2*y = 0
Looking for similar summands in the left part:
-2*y + 6*x = 0
Move the summands with the other variables
from left part to right part, we given:
$$- 2 y = - 6 x$$
Divide both parts of the equation by -2
y = -6*x / (-2)
We get the answer: y = 3*x
