The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right part
Looking for similar summands in the right part:
Move free summands (without x)
from left part to right part, we given:
$$4 x = 4 x - 1$$
Move the summands with the unknown x
from the right part to the left part:
$$0 = -1$$
This equation has no roots
(1/2)*(8*x+1) = (3/2)-(2-4*x)
Expand brackets in the left part
1/28*x+1 = (3/2)-(2-4*x)
Expand brackets in the right part
1/28*x+1 = 3/2-2+4*x
Looking for similar summands in the right part:
1/2 + 4*x = -1/2 + 4*x
Move free summands (without x)
from left part to right part, we given:
$$4 x = 4 x - 1$$
Move the summands with the unknown x
from the right part to the left part:
$$0 = -1$$
This equation has no roots
