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:
$$- y = -14$$
Divide both parts of the equation by -1
We get the answer: y = 14
2*6-y+2 = 0
Looking for similar summands in the left part:
14 - y = 0
Move free summands (without y)
from left part to right part, we given:
$$- y = -14$$
Divide both parts of the equation by -1
y = -14 / (-1)
We get the answer: y = 14
