The solution
Detail solution
Given the linear equation:
Move free summands (without y)
from left part to right part, we given:
$$12 y = -3$$
Divide both parts of the equation by 12
We get the answer: y = -1/4
12*y+3 = 0
Move free summands (without y)
from left part to right part, we given:
$$12 y = -3$$
Divide both parts of the equation by 12
y = -3 / (12)
We get the answer: y = -1/4
