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:
$$- 3 x = - 3 x - 20$$
Move the summands with the unknown x
from the right part to the left part:
$$0 = -20$$
This equation has no roots
12*x+5*(6-3*x) = 10-3*x
Expand brackets in the left part
12*x+5*6-5*3*x = 10-3*x
Looking for similar summands in the left part:
30 - 3*x = 10-3*x
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = - 3 x - 20$$
Move the summands with the unknown x
from the right part to the left part:
$$0 = -20$$
This equation has no roots
