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:
$$48 x = 256$$
Divide both parts of the equation by 48
We get the answer: x = 16/3
16*x-4*(64-8*x) = 0
Expand brackets in the left part
16*x-4*64+4*8*x = 0
Looking for similar summands in the left part:
-256 + 48*x = 0
Move free summands (without x)
from left part to right part, we given:
$$48 x = 256$$
Divide both parts of the equation by 48
x = 256 / (48)
We get the answer: x = 16/3
