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:
$$2 x = 2 x + 9$$
Move the summands with the unknown x
from the right part to the left part:
$$0 = 9$$
This equation has no roots
10*x-2*(4*x-5) = 2*x+19
Expand brackets in the left part
10*x-2*4*x+2*5 = 2*x+19
Looking for similar summands in the left part:
10 + 2*x = 2*x+19
Move free summands (without x)
from left part to right part, we given:
$$2 x = 2 x + 9$$
Move the summands with the unknown x
from the right part to the left part:
$$0 = 9$$
This equation has no roots
