The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
Move the summands with the unknown x
from the right part to the left part:
Divide both parts of the equation by 5
We get the answer: x = 24/5
12-(4*x-3) = 39-9*x
Expand brackets in the left part
12-4*x+3 = 39-9*x
Looking for similar summands in the left part:
15 - 4*x = 39-9*x
Move free summands (without x)
from left part to right part, we given:
Move the summands with the unknown x
from the right part to the left part:
Divide both parts of the equation by 5
x = 24 / (5)
We get the answer: x = 24/5
