The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move free summands (without y)
from left part to right part, we given:
$$0 = y - 6$$
Move the summands with the unknown y
from the right part to the left part:
$$- y = -6$$
Divide both parts of the equation by -1
We get the answer: y = 6
8-1/7*14 = y
Looking for similar summands in the left part:
6 = y
Move free summands (without y)
from left part to right part, we given:
$$0 = y - 6$$
Move the summands with the unknown y
from the right part to the left part:
$$- y = -6$$
Divide both parts of the equation by -1
y = -6 / (-1)
We get the answer: y = 6
