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:
$$10 x = - 2 y$$
Divide both parts of the equation by 10
We get the answer: x = -y/5
10*x+2*y = 0
Looking for similar summands in the left part:
2*y + 10*x = 0
Move the summands with the other variables
from left part to right part, we given:
$$10 x = - 2 y$$
Divide both parts of the equation by 10
x = -2*y / (10)
We get the answer: x = -y/5
