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:
$$5 x = 3 y + 6 z$$
Divide both parts of the equation by 5
We get the answer: x = 3*y/5 + 6*z/5
5*x-3*y = 6*z
Looking for similar summands in the left part:
-3*y + 5*x = 6*z
Move the summands with the other variables
from left part to right part, we given:
$$5 x = 3 y + 6 z$$
Divide both parts of the equation by 5
x = 3*y + 6*z / (5)
We get the answer: x = 3*y/5 + 6*z/5
