The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
Divide both parts of the equation by 12
We get the answer: x = -3/4
16*x+9-4*x = 0
Looking for similar summands in the left part:
9 + 12*x = 0
Move free summands (without x)
from left part to right part, we given:
Divide both parts of the equation by 12
x = -9 / (12)
We get the answer: x = -3/4
