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:
$$10 x = 12 - y$$
Divide both parts of the equation by 10
We get the answer: x = 6/5 - y/10
10*x+y = 12
Looking for similar summands in the left part:
y + 10*x = 12
Move the summands with the other variables
from left part to right part, we given:
$$10 x = 12 - y$$
Divide both parts of the equation by 10
x = 12 - y / (10)
We get the answer: x = 6/5 - y/10
